As a bonus, a fixed high refresh rate I find takes most of the stutter out of iffy games compared to an old fixed 60Hz panel so you aren't losing that much there.
I haven't done the calculations, but 1440p at 175Hz sounds an awful lot for an hdmi connection, so you might lose some top end frame rate options. But if it works...
I would google how to back up your existing video BIOS, or try and get a copy of the one you have from ASUS. Updating that was my first thought, so if you can make that really low risk with a way to roll back...
