Sway/wlroots maintainer here. The older the card, the better the support. If you're not gaming and you have a 9xx or older card, you should have pretty decent support for a workstation type of deal. If you get as old as 7xx or 6xx you start to have games getting playable.

Although note that recent Intel HD should outperform those cards, with much better power efficiency.

For newer cards, nouveau can be a quite sad experience due to nvidia not only making a mess of their own driver, but actively handicapping development of nouveau.
