THE OFFICIAL TECH FORUMS Benchmarks - Heaven 2.1 started by Sean, very cool graphics to watch , etc. - Ya I have a "normal " PC compared to many on this website. I do think it is a heat issue in my GPU's causing the trouble - checked out the heat monitor program as you suggested- I was up to 99% in a few minutes in the GPU area. SO, will check out if fans are working properly, etc.
