I guess I need to look it up to see how it compares.
I was curious about the issues because I am familiar with Nvidia driver installs. I can recover from black screens and 'repair' the driver settings. In other words, I'm somewhat comfortable with the issues as I think I can recover from them. I only have experience with older Radeon cards.
If I use full screen with an ATI card, I'll have graphics corruption? I like to watch movies in full screen (at least, sometimes) so what would that mean? Maybe it's better to get the cheaper ATI card for now?
I was comparing the Radeon HD 5770 and the GTS 250 (I would also consider the newer GT220M Nvidia cards) for as high end as I would go.
Thanks for all these replies for all who answered! Some good and interesting info continuing in this thread!
