This has had nonstop issues since purchase with overheating and screen artifacting. Apple refuses to acknowledge any of this and I've spent the better part of a year trying to get them to replace it.Want to run multiple CC apps at once? Forget it. It bogs down insanely slow.Want to run chrome? Nope.Want to edit in Premiere? You'll get a "GPU" error after applying one effect.Want to plug in another screen? Watch your CPU and GPU temps SKYROCKET into the 80's and 90's. No joke, the GPU hits 90 degrees and the fans barely even turn on. I have to use a 3rd party fan controller just to get this thing to work halfway decent.Save your money and your sanity. DO NOT BUY THIS MACHINE.
