GPU with composite video output (sh.itjust.works)

I have a spare pc that I am thinking about repurposing for arcade emulation. Preferably I would be using a crt, but hdmi to composite adapters seem to have a lot of issues.

Are there any good options for a GPU with actual composite output, that wouldn't be a massive downgrade in power from my gt 710?

You can get GPUs as new as Nvidia's GTX 900s and AMD's R9 300s which will be DVI-I capable (DVI-I or DVI-A are what you're looking for, not DVI-D). You can then use a DVI to VGA to composite adapter chain for perfect, lagless CRT video output.

Thank you, this seems like the best solution. Unfortunately, both of my spare GPUs are dvi-d, so I will still have to buy one.

Like what?

Image quality and delay.

Iirc my old Radeon 4750(? 4850?) had s-video out, which I believe can be converted to composite with just an analog adapter.. not 100% sure on either of those though, heh. And that's an old card (iirc I got it around 2007)

This isn't quite what you asked, but might also be an option: the Raspberry Pi 4 model B has composite output, is fast enough for arcade emulation, and is probably cheaper to buy and operate than an old video card in a desktop PC.
