Hello all. I am buying my first Mac and I need help with a decision. I'm likely buying a 27" iMac with the Core i7 3.4 processor. Will I notice an appreciable difference between the 1GB video card and the 2 GB video card? I have an opportunity to get a 1GB-equipped unit for a nice discount. If I want one with 2GB, I have to do BTO at full price. I don't mind paying full price, but I am curious about the real-world benefits of more video RAM. I am not a gamer. I am an amateur photographer so I do work with Photoshop quite a bit. Not sure if more VRAM helps with photo editing. Either way, I am looking forward to using a Mac.
