Like many others, I am not impressed with the graphics card choices offered for the new Mac Pro. I do some 3D modeling (using Rhinoceros 3D which is available on both Mac and Windows) and rendering (using V-Ray, which is only available for Rhino for Windows), so I guess the 8-core Mac Pro is the right one for me. Because 3D rendering uses the CPU heavily instead of the GPU, the only thing GPU is really good for is in viewport rendering. Viewport performance is quite important though, since it greatly affects the efficiency at which I work. The thing is: 1) I might need 2 monitors. I can't afford Apple displays nor any of the professional IPS displays, so the ones I buy will almost certainly be DVI ones. The mini display port to DVI adapter is a ridiculous $34 and I would rather get another graphics card for the additional performance, unless the price of a graphics card is much much greater than $34. 2) Some people are going to get both the 4870 and a GT 120. I wonder would it be wise for me to get a 4870 and a GT 120? Or should I get two GT 120s? And if I plug one monitor into a 4870 and the other into the GT 120, would one monitor's performance be much better than the other?
