According to benchmarks I could play at max with only 35-50 FPS. Getting the Samsung 590D and a PNY 780 Ti.
You honestly should just get a 27" 1440p monitor for gaming. Those cheap 4K monitors don't have great picture quality, and the resolution is too high for the size. Furthermore, 35-50fps is not great. I've used my 780 Ti on my 4K television, and it struggles in a lot of games. No reason to choke the 780 Ti on the desktop when you can have a better 1440p screen for less.
Also I am not using the monitor for browsing I have my other monitors for that. The 4k is going to be used strictly for gaming and movies.
you dont "need" 2 cards if you are not picky about having the best settings or staying above 60 fps. I am too picky so 4k is not even a consideration for me at this point. plus the horrible Windows scaling would kill it for me for everyday use.
if you looked at ALL games out there then there are actually only a few that you would need to run on medium. even most of the demanding games will be ok on high if 40-45 fps is ok.But max settings with AA at 1440/1600P will look better than medium settings at 4K, so what's the point? 4K gaming only makes sense with dual flagship cards right now like 290s or 780s.
Considered waiting for 800 series? This is a bad time to buy high-end GPUs.

and I am not saying to get 4k and in fact said I personally would not do it. some people dont care about about 60 fps or the best settings though. heck in Metro LL you cant even see the difference between high and very high yet very high runs about 70 fps while high runs about 120 fps at 1080 with plain 780. really even medium looks just fine in that game.
Furthermore, most ultra presets are retarded and apply silly settings such as SSAA. SSAA kills performance by 60-80% depending on the quality and is never worth it. But that's the ultra preset in witcher 2 and I believe Tomb Raider. There are other stupid settings too that are included in ultra presets that simply aren't needed. But SSAA sticks out in my mind as the worst offender.
