re: So, I'm attempting to build a PC and would appreciate some help...

My first question is do you plan on doing any overclocking to your cpu or gpu? If the answer is no or maybe, which it likely is, then you can back down on that mobo. I have been supremely happy with my 120 dollar asrock board which has overclocked my 3570k to a reasonable level. Do not pick a motherboard based on its wifi capability. You have chosen a top of the line gpu which won't need SLI, so there are plenty of PCI and PCI-E slots for an inexpensive ($15) wireless card.

16GB of ram is fine but by no means should you pay 176 dollars for it. The board you chose, and any other ATX board for that matter, will have 4 slots for ram so 4x4 is appropriate. This should not be more than 140 dollars. Will defer to RAM gurus on here who can guide you toward something with low CAS latency and decent clocks for much less money.

Your storage options are too expensive. $140 for 128GB of SSD and $150 for 2TB of HDD is way too much. 2 Tb seagate barracudas should run around $90.

Based on your description you absolutely do not need a $660 GPU, especially at 1080p. I know that the 780s are very nice, but at 1080 you would do well with a 760. If you are interested in looking at a 1440 monitor then you could look at a 7970 or the 780, but it doesn't sound like what you will be doing. You will not be able to tell a difference over 35 fps, so you are dumping a TON of money into performance that you won't utilize.

Case is excellent.

The fractal fans that come with the case are fine, but not worth $17, especially if your case is not windowed so continuity of fan does not matter.

Personally, if I am spending that kind of money on a keyboard I want something mechanical. Do you have a keyboard already that could bridge the gap until you find the right keyboard with the mechanical switches you want for a reasonable price?

Rest of the build is fine.

General notes: overclocking is FREE performance. It is best to utilize the overclocking potential of your system provided that it performs well and is not too hot. Power supply should be something quality like seasonic or corsair. Deferring to others here. Unless you are using your PC to push your home audio system or if you value crystal clear audio and have higher end headphones, then on board audio will be fine. It's one of those things you don't notice until it is there. Do not worry about what consoles are doing. The system we are configuring will trash the next set of consoles. Switching to DDR4 will not be worth rebuilding your system. Whether or not you regret building now will depend on how much you need the latest hardware. Several people on the board are still very happy with their 3 and 4 year old systems.
