I wondered what the difference is beteween NVIDIA cards and ATI cards? Witch one gives best quality and performance? Is the ATI cards just as compitable with different applications as NVIDIA cards?
Just different companies. Each makes graphics cards that compete with the other, and they're usually very close in both price and performance, usually ATI is a little cheaper for nearly the same performance, and Nvidia usually has the absolute highest performance (but around $500+)
