I have the 27" 2011 iMac with the 3.4 processor and the 2 GB graphics card. I upgraded the processor and the graphics card to "future-proof" the machine so it would still run strong later on in its life.
As far as gaming is concerned, this computer screams with power. I can easily play Crysis Warhead on near-max settings at 1080p resolution with a beautifully consistent framerate.
I can also play Crysis 2, Battlefield: Bad Company 2, Assasin's Creed 2, and Just Cause 2 all at max settings on 720p resolution with a buttery smooth framerate.
Left 4 Dead 2 can also play absolute max settings and resolution while getting between 45 and 60 frames per second.
And I haven't yet tried Starcraft 2 at below-max resolution, but at the highest resolution this lovely 27" screen can output, I get about 50 FPS on High settings.
Simply put, the top-tier iMac is great for gaming. You can play almost anything on it.
