Hello! I'm thinking about switching from a Windows PC to the new iMac. For space consideration, I'd really love to get the 21.5". I'm concerned about the graphics card, though - the GT 650M 512. I create content for a virtual world (Second Life), mainly using Photoshop CS 5.1 extended. I believe that card will be fine for PS and tolerable for Second Life, but next year I might start working in either Blender or Maya creating mesh 3D items. Does anyone have any experience working on the smaller iMac using 3D programs? I've got the 27" spec'd out, and am pretty sure that will handle Blender/Maya ok, but I keep going back to the 21.5" because my space is so limited. With either size I'd go with the 1TB Fusion drive, and could bump up to the i7 if that would make a difference in how the card might process 3d renders. Any thoughts would be appreciated. Thanks!
