Upgrading 2K system to 4K - AMD R9 290X2, Nvidia Titan Black or Titan Z ?

Hi all,

I've been rocking a tri-GPU set up with Resolve for nearly two years, with two 3GB GTX 580's for processing and one GTX 285 for GUI. It's been rock solid and perfectly capable for all my work up to 2K (timeline/output resolution, with source media up to 5K being handled fine).

I'm now looking to upgrade to help with 4K timelines and output and also to prepare for 4K monitoring. I'm also looking into storage but I want to focus my attention on current GPU choices and would love to hear your thoughts on this only please.

I use a hackintosh workstation which has 6 PCIe ports and allows me to have four slots run at PCIe x8 Gen 3.0 (equivalent to four x16 Gen 2.0 slots)and one slot at x4 Gen 3.0 (x8 gen 2.0) when fully populated (with one slot blocked by a GPU). I've built 8 hackintosh workstations for DITs, editors and other colourists, so please no comments on this being unstable and dangerous etc, it is only risky in the wrong hands! (-;

My budget is around $2000 for the upgrade so my options seem to be dual Nvidia GTX Titan Blacks or a single AMD R9 290X2.

Any idea which would perform better in Resolve for Mac? I understand CUDA still has a small performance margin in terms of compute performance in Resolve, so looking purely at specifications between the two might not necessarily be indicative of real world performance. Any thoughts on this? Anyone using AMD cards?

The other option is to hold out for the Titan Z but it is a little out of my budget and perhaps not entirely necessary if gains are only beyond realtime or beyond 30 nodes etc. The idea of a single powerful card running on a x16 Gen 3.0 slot (possible if I leave one of the other slots free) seems like a neat solution though.

Looking forward to hearing your thoughts!
