Hi there, Been searching around but can't find an answer to what I need to know. Will hopefully be buying a 27" iMac this week after the back to school promo (hopefully) comes into effect. I don't see myself being able to stretch to the higher end 27" but was hoping to do some light gaming on the machine, mostly under bootcamp. How will/does the 6770M fare at both native resolution and 1080p resolutions? I know high settings are a no-go at native but what about at lower settings? And is going down to 1080p a big disadvantage? I'm looking to play games such as Mass Effect 2 and Portal 2 plus other games that will come out over the coming years. Thank you for any input.
