I have ECS 945GCT-M3 Motherboard. Intel 2160 Duel Core (1.8) cpu. 600w power supply. 2 gigs ram. I ran a 8600gt for about 2 years until it broke. I wanted to replace it with a 8800gt but didn't know if I had the requirements. I wasn't trying to play anything state of the art on it. Just wondering even at medium settings no overclocking, or anything if it would be okay on my system? Thanks for all your help I've been reading tons of information about it. I was just going to get another 8600gt or the Ati equivelant if an 8800gt would not work. Edit: Just noticed it was pci-express 2.0 which my motherboard does not support. Anyone have a tip on best Ati card I could use that dosen't need 2.0? Thanks for all your help I've been reading tons of information about it. I was just going to get another 8600gt or the best Ati that would work on my system.
