I'm building an new 5,1 rig for Final Cut and purchased a GeForce 970 GPU for it. I know that nVidia cards have never been stellar for OpenCL, but I thought it was worth a shot. Then everyone has told me that AMD is pretty much the best and only option for Final Cut, so I purchased a 7970 and popped it in. Comparing both cards with LuxMark Simple Ball, it seems the 970 far excels in OpenCL over the 7970 with 11k vs 8k (my 6,1 with D300s scored almost 14k on the same test). Is the 7970 still superior to any nVidia cards out there and the benchmarks are just messed up, or the 970 actually better then the AMD offerings? What card would you recommend for Final Cut? EDIT: I'm also considering an R9 380, RX 460 or 480 card.
