Hey guys! long time no post! Im wanting to upgrade my Graphics card, but will i require more wattage? Current setup: Asus A8N SLi Premium Board Opteron 175 CPU 10% overclock 2GB Ballistixs Ram X3 SATA Hard Drives X2 Optical Drives Audigy 2 Platium EX sound card Floppy Drive GeForce 8600GTS X5 Cooling Fans Cold Cathode Light 500WATT Modular PSU So, Im wanting to get an XFX 8800GTS 320MB card to replace my 8600 I hear 500 watt will work, 600 recomended. IF my current setup can support a 88gts without having to upgrade my PSU, bonus, but if i do HAVE to upgrade my PSU, then i will have to, just if i can save on not buying a new PSU, woudl be great, but i dotn wanna suffer from power loss. Cheers guys
