Need Help with a choice for gpu

[x3rdStreetSaint]

So I have my pc but im missing 2 ports since i have 4 tv-s as monitors and a drawing tablet, plus oculus rift and I was thinking of buying asus Gt 730 ddr5 for thouse extra ports and perhaps as a physx card. Will that work if i have my main TV , tablet and oculus rift on gtx 1080 and others on gt 730 ? will my gpu be affected negatively or positively  in games or photoshop ? will my power supply be enough ?

Choice for gt 730 is becouse it uses x4 slot so it does not steal bandwith from the main gpu  ,and no i do not have a spare gpu around. and no i do not want o be plugging/unplugging monitors all the time

why not just use the ports on the motherboard? you have igpu, and the mobo has an hdmi and dp.

Does that not use cpu processing power slowing the pc on games that are cpu bound ?

No. It's not using the CPU to render graphics.

ok but would a second gpu be better to offload some workload off the main gpu? and what about it also being a phyxs card? (like buying that second gpu is not a problem im just asking from tehnical point of view)
