Folks need to realize that Intel builds chips to win benchmarks. AMD builds chips to give people what they want.
My point, my i7 920 at work always feels slower than my AMD system at home (a mere quad core) even with a 40GB SSD in the Work PC. Now, this is pure observation, but my AMD system feels way faster in general computing tasks.
It's also worth noting that AMD is using technology that is severely outdated compared to Intel's current process technology and yet is accomplishing 80% or more of their performance level.
That's not too shabby when you think about it. Also, remember what AMD does when they introduce a new architecture. They absolutely dominate. I'm hoping that Fusion holds the same, but you also need to realize that the future isn't going to be about pure performance numbers, which can lie.
My i7 is nice, and I'm glad I chose to have it built for my work PC, but I will still build AMD at home.
