ok so im looking at purchasing a new 15" mbp (the high end model with 1gb of VRAM). now i was just reading some threads saying that because the mbp's have intel hd3000 gfx that the gpu shares something with the cpu? can someone explain this to me more? also will this effect game play? i plan to play diablo 3 on my new machine but im wondering if the 15" mbp will be adequate. what do you guys think? or should i wait until the mbp redesign comes out?
