I will be getting new card graphic for 3D stuff, nothing complicated. I will be modeling, maybe animating etc. So now I got i7 920 - 4Ghz, 6GB of ram 1600mhz, gtx 295.
And with new GPU I will also get 24GB of ram 1600mhz, I think that will help.
So the question is will gtx 660 3GB perform enough or Radeon HD7970, will work better with Maya etc.
