From AnandTech article AMD's Six-Core Phenom II X6 1090T & 1055T ReviewedVael Jean-Paul wrote:If you do same test and running with all real cores..the AMD Phenom II X6 1055T with a overclock like Milos say @3.7Ghz will get the highest nodes!
This cpu is the best Chess/Performance/Price cpu from today!
Next one maybe the Bulldozer...price?

The better way to look at it is to ask yourself what sort of machine you're building. If you're building a task specific box that will mostly run heavily threaded applications (Ed. a chess engine!), AMD will sell you nearly a billion transistors for under $300 and you can't go wrong. If it's a more general purpose machine that you're assembling, Lynnfield seems like a better option.
