I'm looking for some upgrade advice. I've been using a 2.7/16/512 Early 2013 15" rMBP since it was new, working every day as a magazine designer (heavy InDesign, some Photoshop and Illustrator). I use it with a Dell U2713HM connected via DisplayPort and an old school 23" Apple Cinema Display connected via HDMI. I also travel frequently, hence the need for a mobile setup. It's been a great machine, but it's start to feel a bit slow, especially since upgrading to Yosemite. I thought about wiping it out and trying a fresh install, but I've got someone eager to buy my current machine at a good price and thought now may be a good time to pull the trigger on a Late 2013 or Mid 2014 refurb. With the Broadwell delays, should I make the jump or ride it out? The upgrades from Ivy Bridge to Haswell, along with the jump to PCI and 802.11ac WiFi entice me. Running three displays, I think I'd benefit from the 750m and Iris Pro as well. Battery life is not a huge primary concern. I'm just not sure if now is the best time to grab a machine to last me the next two years or so. I don't always have to have THE latest and greatest, and I'd probably wait for a refurb Broadwell machine at the earliest if I don't upgrade now. Thoughts?
