As far as nVIDIA vs. AMD/ATI, I have no preference. I go with the best I can afford. They are both about the same, one is usually a little better, but they switch off. It is usually nVIDIA with the best performance, imo, but AMD has those deals, man. I am training for my CompTIA A+. also, the CPU and both GFX cards in my buddy's comp were once mine. I have owned both, and honestly don't see a difference, other than that the newer cards are more powerful than the older cards, but that is a given lol.
oh, teh lulz...
