Anyone know if I can up my video card with the current CPU in my compy?

And what could I put in there?

I have a Benq Gaming monitor 144Hz, but it was only showing 60 Hz for the longest time until I figured out I needed a 144 Hz compatible cable, and now everything looks beautiful… the problem is… textures do not load evenly, and things get stuck it seems… and if I turn too quickly one way or another, I get disconnected… now I’m running a fairly standard GTX 1060 6 GB video card, 32 GB installed DDR4 Memory … I’m wondering should I upgrade my card and if so what should I get, what options are good for me, my motherboard is a ASUS / MSI (Intel Z370 Chipset) (Up to 2x PCI-E Devices) (No SLI Support)

Thanks for any help!
