I really wanted to know this, but couldn't seem to find any info on the forums, so I spent some time and found this great review... it pits a regular macbook pro against a macbook pro with windows installed and 2 other windows-laptops and shows how they benchmarked with various things.
Really great review, gives me alot of confidence.
