Is the 20% increase in processor and increased graphics RAM (I think they're both XT cards and not a Pro like marketed?) worth the differance of £107? (both with 500GB HD, 2GB RAM) I'll be ordering a new iMac in December, but I'm gonna need to be working out how much money I've got for the semester before I go to uni so I'm needing to decide what I'm gonna get now. It'll be used for all the common student stuff (which both will be fine for), but I also want to be running Bootcamp for few games (Command and Conquer 3 being the newest, and I want it to run very smoothly). I don't need perfect graphics or anything, just good performance. This will also be my machine till the end of uni (3 years), so will the increased performance help a notable amount for this time? My current G5 won't have the legs, and I want to upgrade to an Intel machine ASAP so I have access to a Windows desktop. Not knowing anything about the graphics cards I've got no idea how much they differ let alone if it's worth an upgrade. Any advice would be great!
