Hi all, Iam new here but not in mac world, but just to be sure i got question... I want to build up a cheap mac pro with a old 5.1 tower(2.8 xeon W3530) i want to upgrade it to a xeon W3690 3.46 but it a 32nm it will work? 3530 is 45nm. i read Mac Pro cpu compatibility list thread but i just want to be sure iam not wrong. And is there any stronger cpu i can install? I saw i7 990x can work too but as lower memory bandwidth (1066) so witch can be better? Yes it for gaming (wow). i think the w3690 is better because of the memory no?
