Well I know for a fact my 3700+ bottlenecks my 8800GTS, I guess he is getitng the GTX, he WILL need a decent CPU if he wants to get the best out of that graphics card, if he can spedn that much on a GPU, he should get a good C2D CPU, he will then have no problem. Well, the faster the ram is, the more data it can shift, so I cant see it been a bottleneck :s, deffenitly not since most DDR2 ram is faster than DDR ram lol, and DDR2 aint acting as bottleneck. you can also get like 1000Mhz DDR2 now, ir 800Mhz, cant remember the max though.
