well actually looking at those benchmarks, if you exclude crysis then the 955 is more efficient, it has half the threads that the i7 has and only has about 30% worse marks, so if you turned off HT on the i7 like some serious OC'ers do then you'd probably see the 955 pull ahead, even more so if you were comparing a C0 i7 920 oc'ed to the max via air and a 955 oc'ed to the max via air.
