So I've been debating on getting a 5K iMac or keeping my current machine. I have a 2.26 8-core Mac Pro with 4 drives (2 in raid for the OS install), no SSD, 2 GT 120s and 3 monitors. Honestly, my machine is in pretty bad shape. I was so set on an iMac because the raw speed is comparable to a nMP and I use it for software development. I know I don't NEED the speed and I'm mainly concerned with screen real estate and having a retina display. The retina display really helps with the various iOS simulators. With that in mind, after looking at pricing options, it's just cheaper to gradually upgrade the Mac Pro and it's such a great machine! After all, upgradability is why we all got them, right? So what should I get? Here's what I'm looking at: - 2x W5680 (6-core 3.33 Ghz Xeons) - SM 951 512 GB with Lycom DT-120 - 32 GB of RAM Here's where it gets interesting. I would eventually like 2x24" 4K monitors or, if possible 2x27" 5K monitors (eventually down the road) and I'm unsure about which GFX card to get. I'm looking at the GTX 970, but I'm honestly unsure which one to get. I'm also considering just getting a 24" 4K Dell and keeping my current cinema display for right now. I'm also looking into a 34" 21:9 display as well. Any ideas??
