Well, I am not here to start a competition on which one is the best, I am just wondering what are the major differences between nVidia, ATi and Matrox? What does the other one have, that is missing in the others? As I have a Geforce4 Ti 4200 I know I have: Accuview, nView, nfiniteFX II and Light Speed Memory Architecture II..among other things. I guess it is a matter of choice and so..but I just want to get a general idea on what the other cards have that can make the graphics so sweet! Secondary question: What is the recommended maximum OC for my card?..I wanna push it a bit, but not so much so I cook it or I will get the reverse effect. And what program should I use to OC it? Thanks for your help!
