It will tell you not to bump. Honestly, you did it twice in one hour. There's no such thing as a bump on Tom's.
-What's your budget? That's what'll decide all your parts.
-2500K. It's equivalent to the 2600K in gaming (which I assume is what you're doing?) and costs $100 less.
-8gb RAM. It's not essential, but it's nice to have headroom, and it's only $25ish more. I recommend G. Skill Ripjaws 1600.
-Apparently the Samsung Spinpoint drives are good.
-The optical drive can be anything with good reviews on Newegg. It can be cheap.
-That PSU is overkill for any one graphics card. It can handle two of most non-highest-end models. The PSU that you'll get will be determined by your graphics card(s).
