Hi Guys, i'm looking forward to buy a new mac tomorrow (after 2 years it about time). I focused on the basic 21.5" iMac or the basic 13" MacBook Pro. Is there a huge perfomance gap between those two? i guess the imac is better, because of the graphic card (512 instead of 256) and ghz? I need a new mac for example to cut and render videos (imovie only), mobility is not important and i want to play starcraft 2. iam aware of the fact, that the mac isnt a gaming maschine but its just starcraft 2. Thanks in advance.
