I currently have the macbook air 2011 i7. Its a great computer but the gpu is nothing for gaming. In the near future i hope to get either an alienware or mbp for diablo 3 when it comes out. I have heard that the mpb 15" and up come with dedicated graphic cards witch make them better for gaming. However does that card even compare to the ones available in alienware computers, M14x to be precise?? Is gaming on the mbps comparable to alienware computers? since I'm thinking of waiting for the 2012 mbp any opinions of wether there will be a better graphics card? or even options for customizing it? Will there be ways for me to custom build a very solid gaming machine out of a mbp 2012? I do prefer apple's os. So id rather a mbp, but I'm definitely wiling to switch to alienware. Thoughts? opinions? comments? suggestions?
