###SATA 6Gbps (SATA Revision 3.0)###
SATA 6Gbps has an advertised throughput of 6.0Gbps—or 600 MB/s, by the definition stated above. As I stated in the discussion of chipsets, the number of native SATA 6Gbps ports on the motherboard will vary depending on the chipset. By native, I mean the ports that are actually supported and controlled by the chipset. However, motherboard manufacturers often include additional SATA 6Gbps ports using a different onboard controller—thus, non-native. A general rule of thumb is that the non-native ports will have slightly lower performance than native. While the theoretical throughput is the same, the way the controllers handle an individual storage device will vary.
More on that here: LINK

Keep in mind that these advertised speeds have very little to do with the performance you’ll get from a particular hard drive. They really only indicate how fast data travels from your hard drive’s cache to the computer’s interface. In reality, this speed is heavily bottlenecked by how quickly the drive can actually access that data before it’s transferred, as well as how quickly a drive can write the new data on the other end for data transfers. Even taking SATA speed ratings out of the equation, the slower of the two drives in a data transfer will always be the bottleneck. At this point, there is no 7200 RPM hard drive that will even take advantage of SATA 3Gbps speeds, let alone SATA 6Gbps. This will be explained further in the Storage Drive section.
The number of SATA 6Gbps ports available should only be a consideration if you are trying to run multiple solid state drives in a high-end system. Pretty much any ATX motherboard is going to have at least 2 native SATA 6Gbps ports, and usually more. You’ll have more than you need for the builds discussed here. In fact, if you go with a 990FX, 970, or Z87 motherboard, you’ll have up to 6 native 6Gbps ports at your disposal, further bringing this whole discussion into “non-issue” status. But now you know why.
====Common Integrated Peripherals====
###Audio###
Today’s motherboards are going to have at least 8-channel audio. Most people use a 2.1-channel speaker setup or headphones. Personally, I use a 5.1-channel speaker setup when I’m not using headphones. You can do any of these with any of the audio solutions available on all of the chipsets we’ve mentioned above. Motherboard makers choose different codecs for their onboard audio chips (various revisions of Realtek chips are most common), and they largely all sound the same to most people. If you are an audiophile, you likely already have some general working knowledge of sampling rates, input/output resolutions, and the like. If so, your money and time would be better spent finding a suitable sound card rather than choosing a motherboard based on its onboard sound quality.
###Ethernet / Integrated Network Interface Card (NIC)###
Not much to say about this without getting overly detailed about networking, broadband, ping, and so on. Any modern motherboard worth buying will have a Gigabit Ethernet port powered by some company’s chip, be it Intel, Realtek, Broadcom, Qualcomm, and so on. Some are “better” than others, much like the onboard audio solutions out there. Most people use the integrated NIC, including myself, but there are plenty of dedicated cards out there if you want to do the research. I’ll just leave it at that.
###Universal Serial Bus (USB) Ports###
USB Ports are also a non-issue. The motherboards you’ll be using in a modern gaming build will have plenty of USB 2.0 and 3.0 ports at your disposal. In case you didn’t know, USB 2.0 has a max throughput of 35 MB/s, while USB 3.0 has a max throughput of around 400 MB/s. Huge difference. USB 3.0 also provides more power to devices, which is helpful for the ever-increasing capacity of portable hard drives or for charging a smartphone/tablet.
Most modern motherboards are going to have a mixture of both types, with at least 2 USB 3.0 ports. Nowadays, if you’re buying an external hard drive, it makes sense to buy one with a USB 3.0 interface for obvious reasons. It certainly won’t take full advantage of USB 3.0 speeds, but USB 2.0 would be a major bottleneck. That being said, your decision on how many USB 3.0 ports you need should be based only on the number of external USB 3.0 storage devices you plan to use at once. Your mouse, keyboard, and any other non-USB 3.0 gadgets you might have can be plugged into a USB 2.0 port with no performance loss.
Another USB standard not yet found on current motherboards is USB 3.1, which was announced in late July 2013. It is advertised to have more than double the throughput of USB 3.0, which will come in handy when high capacity solid state drives get even faster and become more affordable for external drive solutions.
###eSATA###
Another common feature of motherboards today is the use of an eSATA port. This is simply a SATA port that’s found among your other ports for integrated peripherals, allowing you to connect an external drive to a SATA port just like any other external drive interface such as USB.
Some computer cases also have an eSATA port available on the front, which is enabled by simply connecting the case’s SATA cable to one of your internal SATA ports. If you aren’t using an eSATA-capable external hard drive right now, there is no reason to buy one and no reason to care about this feature at all. Mechanical hard drives used in external storage solutions are the bottleneck, as discussed above, so you’ll see no performance difference between eSATA and USB 3.0.
###PS/2###
This is an old interface that’s been around since the late ‘80s, used to connect mice and keyboards. Most other legacy connectors have been long gone from modern motherboards, but this one is still pretty common today. Most likely, you’re using a USB mouse and keyboard like the rest of the 21st century. However, since USB support is largely a software-dependent function, it is technically possible to disable USB devices in Windows, either accidentally or due to a virus. If you want to undo that kind of damage, you’ll need a legacy interface such as PS/2 to run your mouse and keyboard until you can get your mouse and keyboard working. I’ve never seen this happen, so this is really just a theory. Obviously, PS/2 ports shouldn’t make or break a motherboard choice, unless you just really, really, really want to use your vintage IBM keyboard.

====PCI Express (PCIe)====
The full name is Peripheral Component Interconnect Express. We’re going to call it PCIe. Wikipedia provides a geeky explanation of the interface, but for now, we’ll just focus on what it’s used for. PCIe interfaces with a variety of components that connect to your peripherals. It communicates with your chipset via “lanes.” A single lane consists of two pairs of wires/tracers. One pair of wires sends packets of data, and the other pair receives.
There are 4 bandwidth levels of PCIe, and they’re commonly known as x1, x4, x8, and x16. This indicates how many “lanes” have access to the PCIe slot. Technically, there is a different sized slot made for each of the 4, shown below:
Most motherboards are only going to have a combination of x1 and x16 slots. The x8 and x4 slots are rare to nonexistent these days. The reason for this is the x16 slots are physically compatible with cards that require 1, 4, 8, or 16 lanes.
A typical motherboard has a combination of PCIe x16, PCIe x1, and regular PCI slots. PCI slots are becoming more obsolete these days but are still used for various legacy needs, such as FireWire cards, and even some sound and Wi-Fi cards.
The x16 slot is of particular importance, because it holds your graphics card.
But it’s not enough to simply choose a motherboard based on the number and type of PCIe slots it has. The more important thing to consider is the number of lanes those slots share. There might be 16 lanes available for each PCIe x16 slot on a motherboard, but there are other factors at play that dictate exactly how many of those lanes can be used at once.
###PCIe Lanes and AMD###
In AMD motherboards, the number of usable lanes is determined by the chipset. AMD’s 990FX chipset provides access to a total of 38 PCIe 2.0 lanes. How they’re used depends on how many PCIe slots are being occupied. If you are running one graphics card, all 16 lanes of the slot will be used. If you add a second graphics card to an available x16 slot, that slot will also use all 16 lanes, for a total of 32 lanes—commonly referred to as an “x16/x16” configuration. Beyond that largely depends on the way the motherboard was made. If there are 3 PCIe x16 slots available, using three graphics cards will usually mean an x16/x8/x8 configuration.
The 970 chipset has 22 PCIe 2.0 lanes available. What this translates to is 16 lanes for a single graphics card, and the number of lanes for a second graphics card depends on the motherboard. The 970 standard only allows for an x16/x4 configuration, but motherboard manufacturers can include chips or switches that control the use and allocation of those lanes to allow for an x8/x8 configuration.
###PCIe Lanes and Intel###
In Intel motherboards, the CPU determines how many PCIe 3.0 lanes there are, and the chipset determines the number of PCIe 2.0 lanes. Intel’s Haswell and Ivy Bridge CPUs (e.g., 4670K, 3570K) allow 16 PCIe 3.0 lanes (and 4 PCIe 2.0 lanes in the Z series chipsets). A single card will get 16 lanes, and two cards would be in an x8/x8 configuration. Higher end Intel motherboards also contain chips that use an active switching function to effectively double the available PCIe lanes (synthetically, similar to the way hyperthreading works).
###Another Variable: PCIe 2.0 vs. 3.0###
While Intel has far fewer PCIe lanes at its disposal than the 990FX platform, there’s another variable at work here: PCIe revisions. Intel’s Ivy Bridge and Haswell CPUs support PCIe 3.0, and their respective Z chipsets support PCIe 2.0, so the Z87/Z77 motherboards use PCIe 3.0 slots for graphics cards and PCIe 2.0 lanes for everything else. AMD boards use PCIe 2.0 slots/lanes. PCIe lane speeds are measured in gigatransfers (GT/s), and PCIe 2.0 lanes have a transfer rate of 5 GT/s, while PCIe 3.0 lanes have a max rate of 8 GT/s.
###What Does this Mean?###
Right now, practically nothing. The cards on the market right now will fit in either slot, but they don’t saturate the full bandwidth of PCIe 2.0 x16, let alone PCIe 3.0. As it stands now, your single graphics card will perform the same on any of the platforms.
I would go into the technical details, but I’m assuming by now you’re willing to just take my word for it: If you were to add a second graphics card at some point, there would be no performance difference between PCIe 2.0 x16/x16 and PCIe x8/x8 except in the highest end graphics cards (such as Titans and dual-GPU cards), and only at resolutions exceeding 1440p. You would get a marginal performance gain (< 4%) at best moving from PCIe 2.0 x8/x8 to PCIe 3.0 x8/x8, and even less of a gain going from PCIe 3.0 x8/x8 to x16/x16 (available on Intel’s high-end socket 2011 platform). Ultimately, the 990FX chipset would have the slight advantage over Intel’s Haswell/Ivy Bridge due to extra lanes if you were going to use more than two graphics cards, but I have always subscribed to the notion that if you think you need more than two graphics cards at any point, it’s time to just upgrade to a more powerful single graphics card. The only situation that warrants three or four graphics cards are for extreme systems using the fastest GPUs available—systems that are likely to be using Intel’s enthusiast platform anyway.
Now, how long the difference will be negligible is up for debate. In single-card setups, which includes all three of our sample builds, it’s unlikely that it will matter anytime soon—not before you’re long overdue for a full platform upgrade, anyway.
Ultimately, I’d recommend a motherboard that supports a second graphics card*. For gaming performance, the most impactful upgrade will always be your GPU. People go through several graphics card upgrades without changing any other component in their system. Being able to simply buy another of the card you already have is convenient and cost-effective, and it’s only achievable with a motherboard that supports the second card (and a compatible power supply, which we’ll discuss in its appropriate section). A motherboard that fits this criterion should have 2 PCIe x16 slots that run in an x8/x8 or x16/x16 configuration. You can also use Crossfire in an x16/x4 configuration (but not SLI), with very slightly reduced performance but still effective.
*Note: Some motherboards only support Crossfire (AMD cards), and not SLI (NVIDIA). It’s important to read carefully if looking for a motherboard that supports both.
