I don't think we're that far away from consumer systems being able to take advantage of high res displays. This build here (http://pcpartpicker.com/p/HZQm23) can already drive 4k on almost all games that are currently out, and it's only $1600. Large manufacturers like Dell wont be far behind with desktops sporting similar hardware. I'd expect consumer (as opposed to enthusiast) 4k gaming on the desktop to start happening mid next year.

that would require a new gpu generation while the current one that is 4K capable (albeit only really smooth in SLI) has just been refreshed.
