At those bandwidths, resolutions seems rather silly to invest in to. Having used high-hz screens for a long time, 60 hz is starting to seem quite broken for me.

120hz+ at lower resolutions first seems a lot more useful, unless one is doing some 360 degree video thing that has relatively very low amount of pixels per degree of angle. Doubling framerate is only double the cost, while doubling width&height is quadruple the cost.
