Hi there! So after seeing the specs and price point on the new Mac Pro, I simply can't justify the expense. I've been waiting 5 years for it! Haha. So I currently have a 2 x 2.8GHz Quad-Core Intel Xeon with 8GB of Ram and an ATI Radeon 5770 1Gb Graphic card. Does anyone have any suggestions to upgrade to a powerful beast? Looking at getting it to the benchmark scores of the top-end iMac at the least. Thanks!
