Ok. I am deciding between these two configurations and I am stuck. I am a somewhat heavy Photoshop/Illustrator/InDesign and I've just started learning programming, which I hope will be something I'm gonna do in the future. I barely do any video editing, and I do not see myself doing it in the future (maybe 2-3 videos from a GoPro a year). I've used 2011 MBA for the past 5 years, and have waited almost 2 years for the Skylake update. Deciding to switch to 15" was the first tough choice I've faced. I do really love MBA portability, but I really don't take it out that much, and I don't have a place in the apartment for a second monitor. Plus I do believe quad-core, dGPU and additional screen real estate is the way to go. So, what makes more sense, .1Mhz increase with 33% more L2 cache or the additional 2GB VRAM that the 460 offers? One other concern are the glitches that mostly users with 460 are experiencing. I am even considering dropping the 460 and going with the 450 to save around $200. Any advice/opinion is much appreciated.
