I'm getting ready to upgrade my old 27" iMac and would like a triple display setup. The iMac 5K in the middle with a 5K monitor on each side. After some quick searching it looks like apple has yet to release a standalone 27" 4k or 5k apple cinema display? That's a shame...seems like they would sell a ton of them to people like me who can't live with less than 3 displays... Do any of you have a 5K iMac with 2 additional displays? If yes, what are you using and how do they work with the iMac?
