So I am trying to decide what GHz (2.1 or 2.4), GB (2 or 4) and a hard drive (160 or 250 GB). I like to do a lot of word processing, but am also a huge Sims 2 fan. I have all the expansion packs and a ton of custom content and would dearly love to play it on a mac. (i'm a 1st time mac user.) Also, i can't decide if i want to play Sims 2 with boot camp, since my game is pc version, or invest in Parellel of Vmware. Any pointers?
