Quadro K6000. Titan Black with twice the VRAM and six times the price tag. Heard ya wouldn't!

Sure it does! 4k video output isn't that hard to do. Rendering a game in 4k is very, very different. A single 1GB 7750 can run LoL on 3x1080p monitors at 60FPS for example. More powerful Cape Verde chips or low-end Bonaire chips could do the same at 4k.
I have linked this review so so many times, but LOOK
. Usually it's to show how important ROPs (2x7850 = 1x7970 + 32 ROPs) are in GPU performance, but this time it's to show VRAM usage. Notice how even at 1600p the 7850s don't take a huge performance hit. Yes, they do lose a small lead over the Tahiti cards, but it's still ridiculously fast and not hindered much. I doubt you'd notice it in the real world. I would love to see somebody test a 1GB 7850/R7 265 vs 2GB 7850/R7 265 vs 2GB 7870/R9 270(X) vs 4GB 7870/R9 270(X) at as many resolutions as possible. If somebody has the capabilities of doing this, then please do. I think that Pitcairn/Curaco is the only current GPU architecture with such a diverse memory setup. GK104 maybe?
Now, for me. I've gone from 2GB 7850s to a single 1GB 650Ti BOOST. I have noticed practically no differences in performance. Of course, the most resource intensive game I play is GTA IV. Don't have Battlefield anything, haven't touched Bioshock since last summer, etc. 2GB is enough for Eyefinity or Surround setups, but I don't know how long this will hold true for. Textures mostly get loaded into VRAM, correct? Why would more textures be loaded at once at 4k over 360p? 36 times the pixels, yes. 36 times the textures and RAM use, probably not. Then you have to remember that the only way to really drive multi-monitor setups or >1080p monitors on ultra @ 60FPS is with more powerful GPUs such as Tahiti or GK110. Pitcairn/Curaco and GK104 still work pretty well, but they lack the graphics horsepower, not necessarily VRAM.
