Nividia or ATI, Intel or AMD

As a cpu i recommned definitely intel I7
as a graphics card the choice is harder, 6970 has a lot of ram which is very important for high res textures and highresolution monitors, here i think is wiser choice amd with 2 Gb ram , i you have enough money then choose nvidia 580 with 3Gb ram its about 10 percent faster.

try to avoid the sli or crossfire, this technology is not mature enough and you will have a lot of headaches with drivers and game support. maybe in future this will change.
