just to be true: we would need to get atleast 200% more performance of gpus to drive a 4k
this means next year gpus need a 75% performance bump - while amd only states 20-30% more performance - nvidia could release a monster but thats not sure and even a monster would only give a 50% performance increase from current cards
going from the 50% performance bump next year we would need a 100% performance bump from 2013 to 2014 and i dont really think it would be possible
this basicly means that we would have to pay around 1000€ to crossfire or sli the highend gpus in 2014 just to play a low-medium settings
why i took 2 years ? intel states that the first high-end consumer monitors will be 4k in 2 years
as for the IBM T221 - its a nice monitor - but quite low refreshrate (it needs quad-link dvi to get 48hz - with duallink it would be only 24hz) - if you really want one - i heard you can buy those for 1000€ when they are used
i mean 4k would be really nice, but seriously - its way to high for the next few years unless a miracle happens for the gpu side, i guess by 2016 it would be fine
