So, this is my first time building a computer and I'm looking for some input from the wise minds here at HWC (flattery, gotta love it

). It'll mostly be used for gaming and simple multi-media (basic video editing, nothing too fancy). I'm also on a bit of a budget and I'd rather try and stick in the $700-800 range.
A part on my list is already locked in as I managed to get a pretty decent deal on it (I'll ** it), but any an all help would be appreciated!
CPU
Phenom II X3 720 $130
Motherboard
ASUS M4A785TD-V EVO $100
RAM
G.Skil 4GB $100
Graphics
*EVGA GTX 260 core 216 $150* (got it a while ago, had a friend verify that it works)
Hard Drive
WD Caviar Black 640 GB $75
PSU
Corsair TX650W $90 (special on right now...)
Case
Lancool PC-K62 $130
Total: $775
Any suggestions would be most appreciated and I'm willing to cut a few corners(I have a feeling I don't quiet need that big a PSU, but its good for future headroom). Although its an awesome case, I may trade it down for something a little cheaper, and suggestions there would be appreciated as well.
Live long and prosper ;)
