Haha. I read that the same way the first time I read it. The commenter means 3 years of renting GPU from nvidia via cloud services.

I think that's comparing to 3 years of GeForce Now at ~22EUR/month for the Ultimate plan, for a total of ~800 EUR. For someone using in 3h/week then you might as well go for the free plan and pay nothing. But renting has while owning can only have financial cost, renting has a hidden cost on top of that. It leads to "atrophy" of the ownership right and once you lose that option you'll never get it back. That will have incalculable costs.
