Been on the fence for while regarding the high refresh craze going around. I greatly enjoy my 27" PG27AQ monitor w/ G-Sync of course. That said, I've never used a high refresh monitor up to this point. I'm not willing to spend the $1500+ ballpark on the X27 or PG27UQ. Just to much for me to consider. I'm considering the XB273K to stay at 4K, but not certain. Possibly a high refresh 1440P, but it would have to be top-notch. I previously also had an Ultrawide 34(non-gaming type), but just wasn't my thing. I guess what I'm asking is if the high refresh is really worth it. Anyone make the 4k 60 to 4k 144 jump? Even 1440p 60hz to 120+ for a comparison at same resolution. Appreciate input on this. Thanks in advance.
