Core i7 860 is $230 at Microcenter or around $300 elsewhere. Comparing avg overclock for the 860 at 3.9ghz to stock 3.2ghz X6 Thuban reveals that X6 would need to be overclocked to have any chance competing with a Core i7:

Also considering how way off AMD's TDP ratings are from actual real world power consumption, I doubt the 1090T will be more power efficient either:
I think the $199 1055T OCed to 4.0ghz would be awesome value however! Also, since most games don't benefit from Core i7 980x, Phenom II X6 @ 3.8-4.0ghz will still be slower in games for minimum frames compared to a core i7. Can't complain for the price <$300, but I am sure if Aigo replicated these benches, the 4.4ghz 980x would absolutely crush the Thuban X6 (and my 860
)
