My old computer's motherboard died and im planning to buy a new computer since the parts are old but the 1070 is brand new so i decided to take it out. My new computer is running 1080ti. Im planning to buy a 144hz monitor for dual monitor. Im thinking can i use my 1080ti on the new 144hz and my 1070 for the old 60hz since im gonna play video games on my 144hz mostly and my 60hz for watching stream and youtube etc. Is it possible to force my 144hz monitor to use my 1080ti while the 60hz monitor to use my 1070 so that i can get the max performance out of the 1080ti?

Video uses very little gpu power. I run dual monitors, game on primary, video on secondary with a gtx660ti with no noticeable effects to fps. A single 1080ti is plenty for dual monitors, even with a 60Hz secondary. The only quirk is if the monitors are different resolutions, that'll take additional power, but not really that much.
Also need to figure in the psu. Big difference in a 650w for the single 1080ti and an 850w for the twin cards.
You'll also need to optimize case airflow, while both cards are relatively efficient, you'll still get all the affects of sli with regards to heat output, top card heating etc.
Honestly, with the prices that a 1070 is bringing right now for used cards due to crypto-mining, I'd be selling that 1070...

yes
all you have to do is run a wire from the 1080ti to the 144hz monitor and then another wire from the 1070 to the old 60hz monitor. I have a gtx 760 running my old monitor and my new 1080 running my 144hz monitor

I don't see all the side affects of dual, separate cards as being worth the few fps difference.
