Got a feeling Freesync/G-Sync nonsense will go on for a while, unfortunately. Not to shun the technology there or the benefits, it is pretty good having seen G-Sync demo myself, but the way companies go about them - eh, I'd rather not and decided not to pony up for that stuff. For now I remain happy with my dual dell u2410 ips display setup, and it'll be a while we'll see some decent ips displays with either variable refresh rate tech, or better yet just one standard and certification to be compatible with both amd/nvidia to replace that vendor-specific nonsense.
Well, some folks run surround setup with 3+ displays. Not my kind of thing though.
