Jagyir :
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)
