Hi all! From my googling, it appears that Display Port 1.2 supports upto 144fps at 1440p. So in this case, is it a waste of money to buy a monitor equipped with a displayport 1.2 and a refresh rate higher than 144Hz?

For reference, this is the monitor I'm buying : Acer Nitro XV272U 2560 x 1440 (IPS). It is available at 144Hz & 170Hz refresh rates. Since both come equipped with a display port 1.2, I was wondering whether the 170Hz was pointless to spend the extra money on buying?
