I wouldn't say that..
with next gen consoles being released this month and 4K displays starting to come down big time in price ..
We talk about 2 GTX780 here, not 2 GTX580.
Seriously the GPU power inflation is not that bad that will render 2 GTX780 useless before 2016. The consoles are having much less powerful GPUs.
And to put into perspective.
[ignore]For 4K monitors to be at around 400-500 quid, we will be well into 2016-2017.[/ignore]
And to operate one of these at high settings,going to need 4x the power a GTX780/R9 290X/TITAN provides, on a single chip.
Losing money now by selling those GTX780s, when there is no alternative to provide the power needed for a future 4K monitor is sensible?
Even if the 4K monitors were reasonable priced today, still we gonna need a QuadFire or QuadSLI to run them with the current gen of top cards (780/TITAN or 290X)
You can already buy a 39" 4k display for $699..
Oops, just saw them in UK for around £500. 290X quadfire!!!!! We going to need some pretty big radiators.
EDIT 2:
How are we going to get 4K with HDMI only? We do need display port that this TV doesn't provide, and any GFX card with HDMI 1.4 will only show 1920x1200
