GHC build times on newer MacBook Pros?

go for 4 cores if the price is not prohibitive. I'm using Q6600 here and 
all cores are quite busy except for the configuration and compilations 
which is done by cabal (if only this cabal would be parallel too!). On 
ARM/Linux -- 2 cores cortex-a9 (OMAP4430) I've noticed that sometimes 
build process strangely occupies just one core but I don't have enough 
resources to search for the culprit and yet majority of times 2 cores 
are 100% busy...
