SC2 is ridiculously CPU limited it's not even funny. I wish Blizzard can optimize the game better so it'll use up 2 or 4 cores for CPU processing. Even the fastest i7 has trouble running the game at max details under ridiculous fights.
For what it's worth, it appears SC2 may be memory limited as well. A Reddit post indicated the significant increase in FPS obtained by overclocking the RAM.

Do you have any links on these updated reviews? I haven't seen any updated reviews from the usual sites I visit. In fact, I don't think tech review sites upgrade their reviews to reflect driver and optimization updates made by the computer or game manufacturers... I rarely see them on AnandTech and Hardware Canucks.
