nah i changed my mind i dont want to be a beta tester,i will wait & see what the pricing on the 6 core 12mb sandy bridge-e will be like (i heard it can be oc at 5+ghz easly) before i decide on my next upgrade but i think its going to be an intel upgrade anyway.

Sandy Bridge-E is a new architecture and completely new mobo chipset.
Ivy Bridge is a massive die shrink on a completely new process technology, with partial mobo chipset compatibility with Sandy Bridge boards.
Better not consider those ... you'd be a beta-tester ....
