Hello, I currently have an old MBP from 2007, with Geforce8600 and 128mb vram. It works fine with photoshop until I plug in my new external monitor, and then the opengl features, like the rotate canvas tool are disabled. I guess its because of the amount of vram. Anyway, Im planning to buy a new laptop soon, and Im considering my options. I don't see any reason for me to buy the higher end 15" model, except maybe the larger vram. I don't do any 3D, only 2D drawings, after effects and premiere, which I know won't benefit from the better video card. So, is any of you knows if the 512MB card is enough to support two high-res monitors (1600-1400 and 1920-1080)? Thanks!
