Hi All! Ok, this is the deal. My old MP2,1 can't sadly run Mountain Lion, cause of the 32bit EFI BIOS. Nothing new... I know, some 64 EFI hack it might be possible.... But i'm looking to build my own, so i can run ML. Now i need some advice, what would be a good CPU upgrade moving from Quad-Core Intel Xeon 3.0Ghz to ??? My current geekbench score is 10471. When looking at some of their score-list its kind of overwhelming, Somehow i get the feeling that when i move over to for example, a Intel I7, by CPU power i'm not much gaining. Maybe i'm wrong. So the question is: what id a -cpu-wise- a good (reasonable) step forward? i'm thinking of a CPU in the price range of 500-700 USD. Or is my current CPU basically outperforms this price range? Looking forward for some of your thoughts!
