I've been looking at this model in the Apple refurb store. Would this be a good upgrade from an Early 2011 MBP?? http://store.apple.com/ca/product/G...-26ghz-dual-core-intel-i5-with-retina-display ... I've been hearing about this "radeongate" issue and although I haven't experienced any symptoms myself I'd rather not go through it if possible. Here are my current specs. MBP (early 2011) 15" hi-res antiglare display (1680 x 1050) 2.0Ghz quad core i7 8GB ram 500GB SSD Samsung EVO 840 (upgrade) 256MB AMD 6490M graphics Intel HD3000 512MB (shared) FW800 Thunderbolt USB2 Boot up and shut down are very speedy. Usually 10 seconds or less. Apps open with one or maybe two icon bounces in the dock. Yet I'm still itching to get a new Mac. Most likely a new MBP. But if or when I do I still can't decide on either the 13" or 15". I'm keeping an eye on the Apple refurb store in case a nicely spec'd 15" shows up with a dedicated GPU as a bonus. I'd most likely never really use the dGPU but for a bit of "future proofing" it'd be nice to have in a few years. But I'd still like to know if there is a big difference in performance between the Iris and Iris Pro iGPU. I've played around with both the 13" and 15" in the Apple store and I really like the 13". I don't usually do more than day to day stuff like web browsing, email, music listening and such. I'm not a gamer but I do have Sim City 4 Deluxe on my Mac. Would that MBP be a good choice?? I'd be light enough to take anywhere and I could dock it at home with an external display.
