I want to get a new laptop with a decent graphics card. I don't care that nVidia's drivers are closed source as long as they're good. I've heard that ATI drivers are buggier and I was wondering which card would be best. I have options like GT 240M, GT 320M, Radeon HD 4670. In theory I think 4670 is fastest, but if it is going to cause computer bugs it's not what I want. So my question is... Am I going to have a stable system with an ATI graphics card, and will I be able to run games under WINE with an ATI card as well as with an nVidia card?
