Hi all, I'm just wondering if I should sell the 15" that I got last year (high end: 4GB ram, 2.66 i7, etc) to buy the high end right now. Is the difference between the first gen and 2nd gen i7 that big? and what about the video card? (GeForce GT 330M 512MB vs. Radeon 6750M 1GB) Is it worth it waiting for the next MBP, that should have the new case design? Thanks! I'm NOT expecting for a clear answer. Just tell me what you think!
