Is the a770 'good enough'?

I recently came across a killer deal on a case, power supply, Intel 14900k, and 128gb of gddr5 6000mhz and I swiftly picked up the lot. I'm going to move forward with a build and I just can't justify current 4080/4090 pricing. I think I'm going to move forward with an a770 considering most games I'm playing (Fortnite, Cities Skylines, Satisfactory) aren't really that demanding. Obviously I'll be GPU limited on this build, but I can get away with running most titles on high @ 1440p right?
