Is the computer in question really "more than capable" if it "can't play the games [you] want to play"? I've used geforce now on my mac before and didn't have latency issues. I wasn't using it for any competitive games where you need ultrafast twitchy response, but I did use if for plenty of FPSes and never had any issues. And I don't have super fast internet, just the basic package from Spectrum. So I wouldn't say it's bad, though admittedly it might not be the best latency achievable in the gaming world.
