i've had an nvidia card for a week and the drivers have given me more grief than the last 3 years of ati put together.
Just goes to show what a subjective thing it really is. I've had both gpu's over the last nine / ten years and am yet to have a detectable problem, this may be due to my low demand of use. Some folk use programs that I haven't heard of so the complexities must add up I guess, possible conflictions etc.


I sympathise since you are obviously having problems when just trying to a bit of gaming, is there any other part of your system that could be the problem?
