A 31.5" 4K monitor has a significantly higher PPI than a 30" 1600P monitor. It's almost twice as dense. No AA should be needed, especially the distance you sit from a 31.5" monitor. This alleviates quite a bit of stress on a GPU.

pretty hefty. we srsly need moar GPU powah
I'd say two highly overclocked Titans would be the sweet spot with a 60 Hz 4K monitor, assuming NVIDIA can get it working with future drivers. Right now NVIDIA can only do 30 Hz 4K via a single DP 1.2 connection. I don't know if it's a pixel clock generator limit, or simply drivers. If it is the pixel clock, that is epic fail on hardware. AMD can only run a 4K screen via MST HUB mode in 2-screen Eyefinity. Pretty shoddy.

Honestly it is very game dependent and demand dependent. I get virtually 90+% scaling in very demanding games like max Crysis 3 in Surround 4-Way, yet other games not so much.
