I'm trying to pick out a new video card, but I can't get one that would need a new PSU, as I can't really afford that atm. Right now I have a X850 PRO running on a 400 Watt Ultra PSU. It has 20A current on the 12V rail. The full specs of the current system are as follows: Intel Pentium Dual Core E2200 @2.93Ghz (BSEL and vCore mod) Cooler Master Hyper TX2 HSF Sapphire Radeon X850 PRO PCI-E VIVO 256MB ECS 945GCT-M/1333 LGA775 Motherboard 2 GB DDR2 667mhz RAM ($3 a stick HP Ram) AOpen 16x DVD/RW Drive Western Digital 'Caviar' 160GB 7200RPM IDE Hard Drive Zonet ZEW1601 PCI RT61 Wireless Card I figure the best I could get is an 8600GT/S as that has even lower power requirements than the X850 Pro. It performs well and I could OC it quite a bit. Any other ideas?
