Hello, I have been thinking about selling my mac pro 8-Core 2.8GHZ and getting one of those i7 Quad Core Mac Pros. From what I've heard, the Nehalem is supposed to be twice as fast? Does that really mean an Xeon 8-Core is nearly identical to a i7 4-Core? Now mine has an ATI 2600 HD. Now how much better is the nVidia GT 120? I am just using Maya and doing quite complicated scenes sometimes. Don't really play games too much. I also would like to take advantage of the Back to School Promotion coming up, and just getting an overall better computer since I wouldn't be loosing very much by selling it, actually would be gaining a bit. It came with free extended Apple Care, and I of course got a $200 student discount, as well as no sales tax. So this offers me a bit of leeway. Thanks!
