Hi all Just a simple question. I have a Mac Pro 2009 2.66GHZ Quad. I plan to upgrade to a hexacore and I have flashed the desktop to 5.1 in preparation for the purchase. I was planning to get the Xeon W3680 But now I am seeing multiple threads about how the W Xeons like the W3680 and W3690 can only run with RAM in 3 banks instead of 4. I am using my system primarily for Final Cut Pro X and Lightroom. And I have all 4 RAM banks filled (20GB - 8+8+2+2) with ECC RAM running at 1066MHz. I'd like to keep it this way. So quick and straight answer - which hexacore CPU should I go for? Thanks!
