Just bought the parts for a somewhat top-of-the-line gaming build with your guys' help!

My next move is buying 144Hz monitors. Which ones do you recommend and why? I'd love an IPS display but it looks like there aren't any below 27". Might be too much real estate if I buy two.

Also, is there any difference between DisplayPort and DVI-DL? I feel like some monitors who have a DP cost more but I'm wondering if that is for a reason. Plus if I'm going to use two monitors, I'll need DP for my 1080ti.

My mind is all over the place, so I appreciate your time, thank you!

EDIT: I forgot to mention my budget is somewhere between $300-400 per monitor. Hopefully I wouldn't need to go much higher. I realize there are some amazing monitors out there.
