I'm trying to find out about the onboard graphics performance of the 8RGA+. I'm not too familiar with IGP, how does this work? The only specs listed are that it's a GeForce4MX, I assume for memory it uses system memory? I currently have a Geforce2MX 32MB card, would performance increase be noticable? Is performance of an nforce2 based IGP motherboard less than that of a motherboard without IGP? Thanks for the help!
