Cheaper for a system with an i5-2500k, with a closed water loop, so when OC, there's gonna be a huge difference with that mac, and crossfire 6870, wich will destroy the mac's 6970m.

8gb of Ram compare to 4.

compare to a Prebuilt, it might seem like a good deal, but I still managed to find a better deal in less than 5min.
