Okay I am trying to run some modern games at acceptable frame rates but most importantly I want to run Gauntlet Dark Legacy on MAME at full speed. (blah blah blah ROMs I don't care though I do seek some help if no one minds) 6750M with 512 MB vs. 6770M with 512 MB How good is the 6750M? I ask because I passed on the discrete Mac mini a while back because I had no interest in Diablo III (mainly due to the delays) but now I have interest in it along with GDL. If the 6750M is good, I'll look into trying to purchase it. If not I'm going PC.
