Thanks for the replies. After doing some research, checking the software: Vue, ZBrush, Maya, etc. I am leaning to the nVidia GTX 690 card at this time. According to e-on, the nVidia cards are better with Vue due to some display glitches they have had on the 6000 series. They told me they have not tested a lot with the newer 7970 cards so can't say for sure. The nVidia 680 and 690 I was told should work fine since they know the 500 series is good to use. Not a lot of testing done with those cards, but they seem to recommend nVidia.

Would love to have a professional Quadro 6000 or new Tesla, but those are not in my budget for just a graphics card. I plan to focus on the CPU with at least an i7 3960X or Duel Xeon and 32GB RAM.
