My question is will an EVGA 770 with 2gb of VRAM be able to run 3 monitors at once, mainly only gaming on the 144hz monitor, then having the 2 other monitors be there to watch Youtube, etc. Maybe game on all 3, but doubtful on that one. I will be getting a 970 4gb in February, will the 970 run the 3 monitors as I asked above?
Also, I know I most likely will not reach the 144hz, hence the 970 later on to get me closer to the 144hz.

depends on the title for 3 screen viewing as well as the resolution. 1080p with 1 144hz monitor should be well within a 770's envelope... but 3 probably would be close to unplayable in modern titles.

really to put this in perspective the 770 is most at home in ultra at 1080p or high/medium at 1440p... and 5760x1080p resolution is almost double the pixels of 1440p.

that said if you're just doing mundane stuff on the other 2 monitors that 770 should be enough in almost every game you play.

Alright, thanks I know for modern titles doing nVidia surround would be damn near impossible.
But now, my final question, will I be able to game on the 144hz monitor whilst still having the 60hz monitors connected and have something streaming or open on them?

yes.
If you don't like the fact that will use up some of your Video memory you could also get a cheap, fanless card and run your secondary monitors from it.

*I think you can run at least one monitor from your Intel iGPU. Make sure "multi monitor" setup is enabled in the BIOS, the Intel video drivers are installed, and plug a monitor into the motherboard. I'd recommend maybe 128MB for video memory in BIOS as it shares some of your System memory (DDR3) but shouldn't need much.

Also,
Your monitor set to 144Hz is always updating 144x per second. You shouldn't use VSYNC unless you can output 144FPS or higher or you get stutter.

A great solution in your case is to force on HALF Adaptive VSYNC which will cap at 72FPS. If it can't output 72FPS then it turns VSYNC OFF automatically so you don't get the stutter due to the synch mismatch but you do get screen tearing.

Force Adaptive VSYNC per game via NVidia Control Panel-> "manage 3D settings"-> GameName->

So again:
1 - VSYNC OFF (if screen tearing is not annoying)
2 - Adaptive VSYNC ON (if you can maintain above 144FPS most of the time)
3 - Half Adaptive VSYNC ON (if you can maintain above 72FPS most of the time)
