I just installed the GTX 970 into my Adobe CC environment.
INCREDIBLE. I created a 4096 sequence, scaled up a 1080 clip to full screen, applied Gaussian blur, Noise, and rotated it on two 3D axes (keyframed), with color correction....
It played back fullscreen, full speed, no dropped frames, and the GPU load never even broke a sweat beyond 19%.
My previous card was a GTX 560 SE. This is not an upgrade, it is a paradigm shift.
Premiere accepted the card after the polite "Enable this unsupported GPU" notice.
Exports (at least to H.264) are taking the card up to about 76%. Wow. FAST FAST FAST
Don't hesitate, grab one of these cards. I cannot wait until my 4K monitor comes in.
