So I've waited for the new iMacs to come out so I can buy one, and they are now here. I always figured the 27" would be the best for gaming, but I have read that the larger screen size can bog down Frames per second because the resolution is much higher. I am curious what the opinion between the two models are. Taking into account that they can have whatever upgrade for each. This may have an obvious answer, but I just wanted to check. Thanks.
