@daniel yes, but no.

You get a decent low-tier rig for 10€ or medium 20€ at nvidia now. Good enough for most modern games. Can cancel anytime (monthly) and even test for free (very limited experience).

For me it's a real option if i compare it to a new low end gaming machine it's feasible. If you have other cheaper options, thinks may look different.

Biggest pitfall: you can't mod the games or easily access game directories.
