Hi all, My cousin is considering getting a new iMac, and he's not sure if he should go with the $1199 model that comes with an Nvidia GeForce 9400M or the $1499 model that has an ATI Radeon HD 4670. He's going to be doing a lot of video editing with Final Cut and Motion, and not so much 3D gaming. But perhaps some 3D modeling and animation. Is it worth the extra $300 for the ATI graphics card, or will he find that the Nvidia card is good enough for what he wants? Thanks a lot.
