Btw if you do decide to run Furmark, then you only need to run it for about 20 mins max.
This will be enough to see if anything it shouldnt occurs, and for you to note down temps etc. and any strange pixels/artifacts appearing on the rendering of the.....erm....furry ring (That sounds so wrong....!) It is designed to stress the gpu so expect the temperatures to go up.....
My HD 6870 idles at 58*C. I'd like to do the Furmark stress test, but what happens if the temp goes too high? Will I 'melt' my card or does the test just stop at a certain temp? Do you see a temp graph on screen as the test is running, if so, at what temp should I stop the test to prevent 'disaster' striking?
