Building/Buying a gaming PC

Kevin, do you have any specific reasons to recommend what you put up there?

Everything seems to cost more, and I guess I'll upgrade if I still have room in my budget. What would be top priority to improve from my current build?

As for the case, I know how big it is. I'm definitely sure I want a full tower case.

Really? A full tower? Those are like...almost NEVER used. Pretty much everything nowadays can fit into a mid-tower.
