hi i need help with 2 issues before buying 8800GTX
1) Will i be ok with my 520 W PSU? It has one 12V rail, 30A
2) Will my Athlon64 4000+ (2.4 Ghz)be a big bottleneck for 8800GTX
Still can't decide between 8800 GTS and GTX. The 320 MB version GTS has attractive price, but has problems with some newer games because of small vRam. The 640 MB version GTS price is too close to GTX, and GTX is so much better.
