You could just punch in AMD X6 Benchmarks and sift through all the results. I use www.tomshardware.com and www.anandtech.com for my basic benchmarking reviews. This article here shows that the i7 920 Nehalem [which has been replaced by the Bloomfield 930] beats out the AMD X6 in most benchmarks. You may or may not be worried about power consumption but the i7's 4 cores suck up less power than the AMD's 6 cores. At the moment I'm a fan of Intel, they seem to be heading in a good direction. I, myself, would only recommend AMD, in it's current state, if you were on a tight budget.
