To everyone who keeps posting about multiple GPU's into s hackintosh and it gives you amazing performance, have you actually tested this? Or basing it on simple computing theory? I've had 2 Titans and a 680 inside a hackintosh and only got a few additional fps in resolve and Adobe cc 2014. Multiple cards was not worth the instability it provided. I've tried Mavericks and Yosemite, to no avail. For anyone who is considering a hack for a machine when working with clients. Save yourself the excuse filled session full of lockups and restarts. Just go with the iMac!
