I found a pair of X5365's on eBay for $100.00 or so, and couldn't pass them up! Tonight I put them in! So far everything has doubled in performance, they do run warmer. I have done a few bench marks. Geek Bench 2 was 5601 now it's 10657 Power Fractal was 37.004 GFlops now 84.540 GFlops I tried xBench and it would not run right, I may need a re-install I did some timings on a 7z compression software. The compressions weren't really any faster (16 sec. per 1GB folder of jpegs), but now I can do more of them at a time, in the same time. I still have a photoshop test to run but I am happy with the results. This puts my cost at almost $600.00 for this Pro, and I can live with that. As time permits I will run more benchs and put them here.
