re: Intel's massive 18-core Core i9 chip starts a bloody battle for enthusiast PCs

Does a non-gamer need the high i-series?

I just do work on my laptop and constantly have Chrome and FF open with like 5+ tabs on each open all the time. I don't use video editing, but some video watching. I feel like my current laptop (about 3 years old) runs too laggy. It's Intel Core i7-2670 (QM) CPU @ 2.20 GHz 8 gb ram and I put in a 256gb SSD.

What are the things that's most important to be able to process a bunch of things, internet surf a few pages on different tabs, etc without lag?

ETA: my fan seems like it's always running with hot air blowing out the side.
