I just recently purchased a 7900gt 256mb card. While running games like BF2 or Everquest 2 the card seems to run the same if not worse on most settings. Im wondering if my PSU dosent have enough power for the card? I have tried reinstalling and upgrading drivers flashing the bios... im running outa options. The Problem lies in playing the games for a short period of time say 20 to 30 mins the textures get real funkey and start doing disco then it hangs followed by a system restart, as if the machine pressed reset all on its own. The hottest the GPU got was around 58c that was running 3d mark the games it dosent go above 47c and it sits at 41c at idle. Im still very new to messing with high end pc parts any advice would help. Probibly more then xfx's tech support.
