Okay, right now I have an iMac with the specs in my sig. However, I have the option to trade it for a MacBook Pro (Late 2008 model) with the following specs: 2.53Ghz Core 2 Duo, 4GB RAM, 320GB HD, 9600M GT 512 MB. My question is, should I do it? There's really no need to (or not need not to), but I'd kind of like to have a laptop just for that portability and (this sounds weird) I'd kind of like to make a change in the way that my computer looks. Is the 9600GT comparable to the 8800GS in my iMac? I know the 8800GS is better than the 9600GT, but by how much? Would I notice much of a difference in playing games? Also, I'm worried about downgrading from a 24" screen to a 15" one. I like all the screen real estate I have right now, but then again I might buy an external monitor for the MBP. Should I switch?
