I have a 16 core machine at work (with 48GB of ram, a perk of the job :)). GHC can saturate them all. Can validate GHC in well under 10 minutes on it.
I also just got the 15" core i7 2.3GHz less then a week ago, it's a very nice machine so I would recommend it. But yeah just getting the 2.2GHz is the better value for money.
