GPU Upgrade

[Auchhior]

Hello, I wanted to upgrade the GPU in my system. My current specs are

 

CPU: i7-3770(non-k)

Mobo: MSI H61M-P23

RAM: G.Skill Value 16 GB (2x8GB) DDR3 1600 mhz

GPU: EVGA GeForce GTX 1050 Ti

PSU: Thermaltake Smart 600W 80+

Monitor 1: Samsung LS24F350FHNXZA at 1080p & 75Hz

Monitor 2: Acer G246HL at 1080p & 60Hz

I've been doing research and have gotten conflicting information about what would be a good upgrade, from the 1060(6GB) all the way to a 1080Ti and a lot of options in between. So I wanted help on what would be good for my specific system. 

 

Right now I play at 1080/60 most of the time in sp games and 1080/75 in titles like League of Legends. At most I'd swap one of my monitors with one at 1440p/144hz otherwise I would stick with my current monitors. I'll also be swapping out my cpu cooler with a Hyper 212 Evo at the same time I swap out my GPU, in case that factors into your decision at all.
