With the introduction of 4K do you plan on support QuadHD (or is his just Ultra).
My monitor resolution is 2560x1440 and I tend to run at 60fps with a GTX 960 Card set at Ultra. But I agther the resolution is 1920x1080. Are you planning on supporting 2K?
Running at 4K kills the FPS such that it drops to about 10FPS.
