First off please "macs arent made for gaming" posts. I know, but I bought a mac for work purposes with gaming on the side so it fits my needs.
I have the 2010 i7 2.67 ghz model of the 15" macbook pro and I usually get fair fps pretty much everywhere, but it lags a lot.
Heard the new generation of intel core processors and the ATI HD 6750M really give the current model a huge performance boost. My friend tells me specifically for WoW, he bought the 2011 model and noticed like a 20-30 fps performance boost(he has the lower end 2010 15" model).
I think I'm returning from a break from wow for the summer, and I kind of want the newer model. Is the performance boost worth selling my current macbook pro and getting the 2011 15" macbook pro model(with the difference being only around~$300)? Call me crazy, but if the performance is huge all around the board, I think its a good buy. What do you think?
