idk, i havn't ran it for a long time yet. I was overclocking the card more. Got it to 540mhz core and 570mhz mem without much problem. The idle temp was 43C, 1 degree higher than stock. I get better performance playing battlefield vietnam with 64 bots and highest res now. I'll check for artifacts tomorrow.
How long should you leave the artifact checker on for? Because i had it on for 5 minutes and the card shot up to 69°c infact it got up to 65 from 48 in about 1 minute.
i'd leave it on for around 5-7 minutes, because when i ran mine, it shot up from around 38C to 62C within a minute, but it was stable around 65C for the rest of the test.
i was using the "show 3D image" thingy at my overclocked speed and it the temp stabalized at around 67 degrees and i was getting around 210fps on the rotating fuzzy cube.
