I am not usually in the market for Xeons so forgive me if this is old news, but according to Barefeats, the 5,1 Dual Core Mac Pro can have its Xeons upgraded to be faster than the nMP! Not only that, but this company called "editbuilder" is actually selling them pre-upgraded. Dual 6 core Xeon X5690 3.46GHz 128GB PC1333 RAM 1TB Samsung Evo SSD drive (Fastest SATA SSD on the market) 4x4TB HD (550MBps at RAID-0) [ you clearly need to back this up immediately ] GTX570 -just one card $9,100 for this ridiculous machine, but it blows the rumored Geekbenches of the nMP away. [Edit: Apparently the application was run in 32 bit, Primatelabs did their own Geekbench using the same processors, to show a better estimation. The "frankenpro" by Editbuilder still dominates. To be clear, Geekbench is estimating using numbers from the exact same processors Apple is using for the nMP.] The fastest nMP will reportedly use the 12 core Xeon E5-2697 v2 at 2.7Ghz - 3.5ghz Turbo. Here are the upgraded Mac Pro benchmarks. On Integer performance, the Upgraded Old Mac Pro is 73% faster than the leaked benchmarks of the old one and 29% faster than what Geekbench estimates the nMP will do--this apparently correlates well to CPU-intensive applications. On floating point, the nMP barely wins, however, with a score 3% faster than the upgraded old one using only the leaked benchmarks. I'm not saying this is a good value, those are some ridiculously expensive components. 16GB DIMMS aren't cheap (~$1,200 for 128GB?), the Processors are $1670 each (x2), and that SSD is $600 by itself. What I'd like to see is them include a 2nd PSU and a couple of GTX780's in there!
