Rough guess - CSGO on one monitor and web browsers on the other monitors would be OK, four 4k videos would probably not be ok. I looked up the specs for that GPU and they're roughly 1.5 teraflops compute and 20 gigapixels fill rate, so in theeeeory you could do a couple hundred FLOPSs and a dozen draws per 4kx4 pixel per frame, but in practice you're never going to get close to that.
