Similar position myself. Currently have a AW3418DW but the blacks are providing to be a real issue in dark games. Other than that, it's fantastic.i was looking at the AW3821DW, but 24% more pixels doesn't seem worth it. Especially for the price and lack of HDR10, sRGB etc.
I have been looking at other monitors, but not really sure what to do. I love how sharp everything is on an IPS panel, and recently got a Dell P2720DC for my works MacBook. Not a high end monitor by any means, but the text is no where near as clear, and that's my main issue switching from IPS back to VA.
Could do with someone releasing a UW 34" OLED monitor..
