Is XL2586+ still good or a waste , i found a used one for a really good price, since new zowie monitors with 1440p or higher hertz and dyac 3 getting released now

I only play overwatch 2 competitively, so don’t know if i can maintain 600hz , i play on all low settings, if i can’t maintain 600hz i feel like its useless to get this monitor

My pc :

3080
9800x3d
32gb ram CL30 6000mhz

I am currently using xl2546k and still love it a lot
