Mac Pro Nahelam vs. Cell Processor (AKA PS3)

[coolio2654]

Hey guys, this is probably my first casual question (that doesn't involve my comp getting blown up) on this site, hehe.
I recently read that Crytek just discovered that Crysis 2 will max out the PS3 CPU-wise 100% (read the story here http://www.gamasutra.com/php-bin/new...hp?story=23898). I know that PS3 Cell Processor is really good and was wondering if my future Mac Pro could possibly max Crysis 2 out as well. I'm thinking about the 2.66 quad-nahelam with 6Gb RAM. Would this mac pro beat PS3 CPU-wise, if it wouldn't, what version of it would it take?
