Hey all!
I just wanted to report in that I picked up Skyrim the other night and am playing it flawlessly on Medium graphics settings, with high textures and high shadows at 1440x900 resolution! My Macbook Pro specs are as follows:
Core i7 CPU 2Ghz
4GB DDR3 RAM 1333Mhz
ATI Radeon HD 6490 Gfx with 256mb GDDR3 RAM (I refuse to call it AMD

)
Catalyst 11.10 drivers
Windows 7 Ultimate Edition 64-bit
I know the minimum specs on this game call for 512mb gfx cards but I think Bethesda was exaggerating a bit, since my card is running it just fine on Medium and its a 256mb card. So to any who are wondering, YES, the low-end early-2011 Macbook Pro CAN play this with only a little bit of stuttering every now and then!
ABSO-FREAKIN-LUTELY FANTASTIC GAME TOO!
