And btw the AMD Phenom II 1090T (six core) processor only beat the Core i7 920 (quad core) on one single test in this comparison. There were 11 comparisons total.

The AMD 1090T is the flagship AMD processor
The Intel Core i7 920 is NOT the flagship Intel processor. Right now the Intel flagship is the Core i7 980X, which is expensive. However, the following Core i7 processors are all better than the 920: 930, 950, 960, 975, and 980X. So really, take any one of those and they will perform even better than the 920. That says an awful lot about Intel versus AMD.
