hello since I am a new guy here I will try my best to stick to the letter and be as clear as I can. so i have a mac pro mid2010 quad core with the stock intel xeon w3530 @ 2.8ghz socket s1366 and intel qpi interconnect 4.8gt/s i was planning to purchase a intel xeon w3680 which is six core at 3.33ghz use the same socket as the stock processor s1366 but here comes the trouble for me, I noticed that my quad core xeon has 45nm lithography and intel qpi interconnect speed at 4.8gt/s then the six core processor i am interested to buy has 32nm lithography and 6.8gt/s does this mean that my mac pro's socket doesn't support 32nm and 6.80gt/s please if anyone knows anything that can help you are more than welcome to help me . in conclusion i am also seeing the w3670 xeon six core at 3.20ghz has the same qpi 4.8gt/s but 32nm lithography which processor can i use to upgrade my mac pro ?
