I am rebuilding an older Athlon XP AGP system. And I am not sure which of these 2 cards to go with. 1st: ATI Radeon X850 Pro. This is my old card that I have used and always been happy with. I have done the BIOS mod to XT PE and installed a Zalman cooler and mem heatsinks. In WoW in could run high settings and get 50-60 fps with temps in the 50's. 2nd: ATI Radeon X1650 Pro. This thing is stock. I have done some web research and cant get a good answer. Personally, I think the X850 will be the way to go. But, it is also uses much more power. Kinda torn here So, give me your opinions.
