Recently I OCed my X800GTO to 570mhz core/530mhz memory from 400mhz core/490mhz memory.
After running a high-GPU intensive task for couple hours, such as doom3 and Farcry, my GPU gets to around 79 degrees celsius with fan speed at 95%.
When I run my GPU in silent mode, which lowers my card to 280mhz core and 343mhz memory, my GPU cools down to around 40 degrees celsius with fan speed at 54%.
All tests were done using the TriXX OC software that came with the X800gto. My maximum OC, 570 core/530 memory were done using the auto OC detection feature.
Question: I need my GPU to run at maximum speed, as on 1600 by 1200 with high details on modern games, without OC my card laggs behind -- will this damage my GPU or should I say WEAR OUT my GPU too fast (I want the card to last at least 3 years)?
