I'm looking to buy a refurb from the Apple store. I've got it narrowed done to 2 (for now) and my main issue is the graphics card. One has an Intel HD Graphics 3000 and AMD Radeon HD 6750M and the other has a NVIDIA GeForce GT 330M graphics processor with 512MB of GDDR3 memory. I'm only looking to play World of Warcraft and Diablo 3 really and I'm having trouble figuring out which one would be better. Keep in mind I'm currently rocking a 2006 MacBook Pro with an ATI Radeon X1600. Any advice would be appreciated.
