I am building a new computer, and I'm wondering if I will hit any sort of bottle necks. I'm getting a Quad 8200 2.33ghz processor, 4GB of ram, and the ATI 4890 by Powercolor. The only games I play are the usual ones from Steam(Portal, L4D, TF2, HL2), Fallout 3, and Fable Lost Chapters(Old I know, but I love being evil . Anything you would recommend upgrading? The reason I'm going with the 8200 is because it's a decent price and from what I've noticed on other people's computers it seems to perform quite well too.
