AMD PHENOM II X6 V\S INTEL

In terms of multi-threaded performance, the Phenom II X6 1090T Black Edition is roughly equivalent to the Core i7 800/900 series. The Phenom II X6 1055T would be closer to the Core i5 750, IIRC. In single threaded performance though, it seems like the Core i7 and Core i5 are still faster.
