Hello one and all, what a marvelous day it has been here in somewhat sunny england for a change. ANYWAYS, getting teh macbook pro, installing XP after hearing people say..."will run bf2 fine on meduim..." etc, counter strike source on high, all the rest of that jibbering gaming talk. So, I'm going for the base - 512mb of ram, but most notably it has 128mb GPU rather than 256mb which the others features. Obviously, someone as technical minded as me can upgrade the ram in a snap, (snappy doo da), but what about the GPU? Is that gonna affect peformance a lot? Cheers doods.
