Looks nice, for $5 more you could get a quad-core 3GHz processor, but you'd need to find a compatible mobo and it wouldn't be on the new AMD A series with the discreet-class graphics (which is what I assume is what your graphics card is going to be). I don't play TF2 (not crazy about FPS), but I play Minecraft on my early 2011 MacBook Pro 13" with a 2.3GHz i5 and integrated graphics. Getting almost 30fps on fast graphics, render distance far, smooth lighting on, bobbing off and it plays great. The A series is a heck of a lot better. From what you've got here it looks like you're all set. Looks like a good build!
