I've found it to be a pretty good product, at least for my use case. I only have an hour or two/wk to play games these days, so it doesn't make a ton of sense to spend the time and $ to buy and install a new video card. So I got whatever the bottom paid tier is for GeForce Now and, while there are occasional lag-spikes and jitters, they're generally rare enough to only rise to the level of minor annoyance. If I wanted to spend a lot of time playing games, especially multi-player ones, I don't think it would be a good substitute for using my own machine, but for being able to occasionally dip a toe into a game when I get the itch, its a pretty good deal.
