Yet another should I, should I not, on the fence kind of thread I'm a graphic designer who is happy with the performance of my system for daily design use (Photoshop, Illustrator, InDesign) but like many of us, would like to have the latest and greatest. I've been lurking around lately reading up on the release of the 2013 Airs, and coming from a Mid 2011 11" 1.6/i5/4gb, I'm really considering upgrading my system to the 2013 11" 1.7/i7/8gb. A few perks that I obviously would gain is USB 3.0 (which would come in handy for me since I normally keep my work files on my external hard drive and work from there), and of course, the performance boost... My benchmark now is 5125, and I see the new 1.7/i7 receiving about 8373. I'm not a big benchmark kind of guy, and am wondering if that is a substantial speed bump. Anyone else make the upgrade? Thanks in advance!
