Hello all. I have a late 2008 Unibody MBP and I will be wanting an upgrade soon. I did a little bit of research regarding the jump from Sandy Bridge to Ivy Bridge and processor-wise it looks like the improvements will be quite minimal (5-10%). I wanted to know if anyone had a good idea of how good the graphics improvements would be for the next gen MBP? I suppose I ask because this would be the difference between spending the extra money on a newer MBP versus just buying a refurb for a couple hundred less?
