If time is money, how much would it cost you to play with those configs vs getting the MacBook? Every time I've done the math, I end up leaning towards the MacBook.
It's not exactly comparable to my MBP, but neither is the cost! The FW cost me about $1,100 all-in and the MBP was $2,900 (both 32GB/1TB).
