i always figured ati for a bunch of windoze fanbois. seems they have really good performance while running d3d, but not so good on opengl. nvidia on the other hand seem to want to support as many platforms and apis as possible and are actually interested in marketing to the linux (and osx?) user. i pick nvidia becasue i want something that has comparability in my favor. i know d3d games, after a couple new versions of direct x, just wont work very well or at all. its sad that a lot of good games just cant be played anymore without a nostalgia rig or some kinda emulation software.
