The subject system includes:
P4 Prescott 3.0Ghz
Chaintech Summit MB
XFX 6600GT
1024MB Corsair XMS DDR3200
Creative Soundblaster Live
PCI Modem
Ethernet Card
2 80mm fans
Sony DRU-710A DVD Burner
Thermaltake 430W PSU
Would that setup have enough power to run a 7800GS instead of the 6600GT? I realize the PSU only has 18A on the 12V rail but I've read that the 7800GS only draws about 30W more than a 6600GT. If I remember correctly, the extreme PSU calculator puts the system at around 280W at peak usage, but this doesn't specify rail amperages. I found an eVGA 7800GS for $265 AR and think it's time for an upgrade, but don't want to have to upgrade the PSU too.
