With the forthcoming lousy Intel graphics chips in pretty much all macbooks and imacs, gaming will be rendered completely USELESS in OS X.
No video card on an imac or macbook could handle that kind of resolution unless your significantly crippling the quality settings or playing a very old game.
I like the resolution, but GPU options in apple computers has gone to *****. It used to be pretty bad.... now its next to non-existent.
What are you talking about? Macbook Pro comes with NVIDIA GeForce GT 750M
and the iMac can be configured with NVIDIA GeForce GTX 780M 4GB GDDR5.
My Macbook Pro can run Bioshock Infinite on high settings better than my desktop pc with an AMD HD6850.
