I'm not dismissing those that have had problems with NVIDIA and ATI cards flickering. However, making blanket statements is not going to help solve anything. There are people out there (like myself) who haven't had a single problem with their 5900 Ultra or 9800Pro. How can we explain that?
I'm just saying that some balance is in order IMO. I would be so mad I could spit too if I was stuck with a card costing that much money with the kinds of problems I read about. After spitting, though, I'd RMA the sucker and move on (hopefully).
