I picked up a passive pciex1 GT730 a few years back when W3 came out for a physx card. (but an update removed that funcionality from that game
The card has Nvidia HDMI 1.4b so it will do 4k60, but at 4:2:0 chroma color compression which is black/white at 4k and color at 1080p. It doesn't look that bad, is most apparent on desktop text and hard to notice in games and movies. Kepler DP1.2 does 4k60 at 4:4:4 just fine, but this card doesn't look like it has that.
You can also bios flash them to extend their range up to Kepler max of 1200-1250 and remove boost if you just want to play around (I flashed mine to 1020 base clock and that lets AB reach high as the card will go), but they are still comparable to a Skylake igpu. But they do remove graphics load from your cpu and give you access to Nvidia control panel so there is that. And the Zotac one I have stays in normal gpu temp range with it's passive cooler.
Good for display and igpu class games.
