A little googling is the best idea for these types of things.
Personally, in the last few years, AMD has really dragged their rear ends up and down the road when it comes to improvement on their processors. Yes, they have gotten faster, but not by leaps and bounds.
Intel is definintly the reigning champion right now, and their i7 processors are screaming fast and the Xeons are even faster. I have the i7-2600k, and I would never trade it for anything with AMD on it.
From the look of that page the AMD is slightly faster, but the Intel processor has so much more built in technology.
Plus, if you overclock AMD wrong *POOF* goes your processor. You overclock a Intel wrong, and it just grinds to a halt and says FIX ME!
Definintely spend the extra buck, and get a better product in the Intel.
