I'm planning on buying one of the new 20" Intel iMac's within the next few weeks, and I was looking for a little advice so I can make the best purchase. First off, what are the benefits of having the upgraded 256 MB of VRAM? Is this mostly just for gaming? Because I'm not really much in to gaming, so if that's all it's good for, I don't really need it, and I can save a little more money. But if it could benefit me, then I'd definitly want to add it on. I mostly plan on using it for pro applications like Pro Tools, Photoshop, Final Cut, Flash, and Dreamweaver. Does VRAM even help with these apps? Or is it relatively unimportant unless you're gaming?
