Is 1440p really worth it? There's no longer the choice to use 1080p and I'm not sure the IQ is really worth the price in power you pay.I have a 2060 with 1440p/144Hz and it's fine.
Yes, I don't really reach 144Hz in demanding games but even at 6o or slightly above (or below) it's a massive improvement over a display without VRR.
The display will also last you for a long time, and by the time you upgrade your graphics card you'll get more power for less money than today (ideally) and will likely still be using the display for a long time.
Even if you do end up upgrading your display to 4k or whatever, you can keep using it as a great secondary monitor.
VRR though, totally behind it.
