I'm off to buy my son a new imac, he is going to get the 21.5 inch model, I'm trying to decide if it is worth $300.00 extra to upgrade to the next model up. the $300.00 bucks gets a 1tg hd over 500gb and a AMD Radeon HD 6770M with 512MB over a AMD Radeon HD 6750M with 512MB graphics processor, that seems to be the only two things. he wont even need 500gb so the graphics card would be the only sticking point, is it worth the $300. extra or no? ETA: it does look like one has a 2.5 ghz intel i5 chip, and the other has a 2.7ghz i5 intel.
