I will post pics of my absoultely ridiculous setup that I was blessed with.... but anyways duel 27" cinema LEd displays, fully maxed out mac pro 12 core, max processor speed, SSDs, world's fastest graphics cards, etc... But I obviously chose to keep the RAM to MINIMAL when checking out at the apple store online..... would of chosen nothing if possible. Anyways: DOES IT REALLY MATTER THE MANUFACTUR WHEN IT COMES TO MAC PRO RAM? I've been told it doesn't? Yes, I actually do need as much ram as possible. Get into that later as well as post pics... But SHOULD I JUST GO WITH 48GB (3x16GB) DDR3 ECC PC10600 1333MHz SDRAM ECC for Mac Pro 'Nehalem' & 'Westmere' models[/B] ?? What seems to be most advertised and I know is very reliable and has solid history and reviews...... OWC - other world computing...... And I can get 2nd day fedex shipping within 30 minutes from now MAX if I order. NEED THIS ASAP. But like most people.... im only 23 , trying to ball on a budget... How can this be legit??? http://www.amazon.com/64GB-PC3-1060...d=1360121785&sr=1-25&keywords=64gb+ecc+memory I mean ....... It's what, 150 cheaper than OWC? And 64GB instead of 48GB??? Unless I'm just being blind and not seeing something obviously (I don't care if latency is CL9 or CL7..... there is not a world world effect) SOMEONE KIND PLEASSE HELP ME WEIGH IN???? CAUSE THIS IS VERY CONFUSING TO ME. IS THAT DEAL LEGIT? JUST PLEASE I'D GREATLY APPRECIATE IT!!!
