Im still very new to computers. And learning more and more each day. The more I ask ( silly question or not the more I learn )

 This is my set-up:
 i7 non-OC
 MSI 970 GTX
 z97x gaming MOBO
 corsair 750w PSU
 Samsung 850 pro 512 SSD
 4tb Toshiba HDD
 16gb ballistix RAM

 Here's my question.
 Is it ok to run 2 144hx monitors and a 60hz monitor on this single GPU?
 Or do I need another 970 GPU?

 *** I'm not much of a gamer, but when I get some free time I would certainly like to try ( *cough cough* We have a 2 yr old and 2 month old so we have minimal free time ).
 1) "Why 3 monitors?" Why not? I have the deskspace and I have extra monitors ( I only have 1 X 144hz monitor this tie )
 2) "What do I use my PC for?" INTERNET. Browsing. Surfing, videos etc... Nothing demanding. But some point in time I'd like to dabble into picture and home video editing etc... Plus I always have multiple tabs and windows open once so the more monitors the easier it is.
 3) "Isnt this an overkill?" Yup.
 4) "Why 144hz?" Have you seen these things? WOW!! I bought an acer 24" 144hz 2 months ago from newegg on sale. Watching videos is amazing.

 So we know I have an overkill set-up for what I do. Yes this money could be put elsewhere etc... And I don't need any of this for what I do. I know that. But it's fun. I see it like this: Why does the guy down the road spend $40,000 and 6 years rebuilding a 1972 muscle car in his garage and INVEST $18,000 on shiny chrome performance parts when he doesn't drive it in the RAIN? Only put on 1,000 miles a year and never goes above 65mph when the car will do 160 mph? Because he can. And he has fun. This is how I see it.

 Ok enough with that.
 1) Can I run 2 144hz monitor on a single 970? a)will there be performance issues with 1 GPU?
 2) Do I need a 2nd 970 GPU?

 thanks everyone
