Hey there, Sorry for another thread on this but I'm looking for some input from those of you who own the 15-inch MacBook Pro with Retina display. I'm currently looking at purchasing one of these models in the next two months (likely towards the end of February to the end of March depending on finances) as an upgrade from my 13-inch non-Retina MBP, and I'm kind of torn between the two options. For the most part, I do a lot of multi-tasking... this includes your standard stuff like web browsing, email, listening to music, but I also do some photography and tend to shoot RAW so I'm editing in Adobe Lightroom a fair amount. I also do a bit of technical support stuff as well and as such would possibly run a couple virtual machines (not necessarily at the same time). I also do a bit of web design and coding now and then. I also do a bit of gaming, although not a lot... I play StarCraft 2 and Diablo 3, and I do tend running those at a decent resolution with medium/high settings (or higher if possible). How does this work on a Retina display in terms of the resolution settings? Just like a non-Retina MBP? What would happen if I were to use a scaled resolution (such as 1680x1050 which I'm likely to do)? The full list of applications I run include Safari, Firefox, Mail, Messages, FaceTime, iTunes, iMovie, GarageBand, Pages/Numbers/Keynote, BBEdit, Lightroom, Photoshop, VMware Fusion, StarCraft 2 and Diablo 3. As mentioned earlier, I do multi-task a lot so it's not uncommon to have 5 or 6 of these at least running in the background at any given time. The two options I'm looking at are: 2.2 GHz / 16 GB RAM / 256 GB SSD / Iris Pro Graphics - $2099 2.5 GHz / 16 GB RAM / 512 GB SSD / Iris Pro + GeForce GT 750M Graphics - $2699 Cost wise I may be able to get either of these from Apple's Certified Refurbished store online if they are still available on there when I go to purchase, and my employer also has a discount through Apple that would knock about $150 off the price of each so I'm not too worried there. Which one would be the best choice for my usage pattern though from your experiences? I'm looking to get at least three years of solid usage out of this computer, so it's important that I get the right model at this time versus having to do another upgrade in a year or two. Thanks for the insight and advice, and have a great day.
