I have been having problems of late with my card (Temp/Freezing - using ATITOOLS the GPU temp at boot averages @ 41.4 with enviroment temp @ 37. Then after 10 mins running MFME (fruitmachine emulator) temp averages @ 55 with enviroment temp @ 47. Then @ idle the GPU still gradually rising to around 57. Then after 10 mins or (crash/screen freeze) of a game (tested with - Scarface, Just Cause, San Andreas or even PDC World Championship Darts) then with a quick reboot temp averages @ 86.4 with enviroment @ 53. It seems to me the GPU is definantly overheating, so I phone the nice people @ Crucial (card only 8 mth's old) and they say they will replace it, but not with original as they no longer stock, but with an X1600 PRO 512MB. Is this a fair swap ? I know the X800GTO has GDDR3 memory and the X1600 PRO has GDDR2 but I am unsure about the other features/performance of each card. I am not an overclocker and the power supply is suficiant, and case/cpu/mb are all @ good temp's. Also the card has run OK since June. Any help feedback much appreciated.
