Question Best of these three Graphics Cards?

[box o rocks]

This is a bit of an odd combination, but they are a GTX 1070, RX 5600 OEM, and an RX 590. Oldies by today's standards for sure, but all in good shape. And they are the only 3 that I have left to match up with a legacy i5-7400 for upgrading a PC for someone. I suppose the machine will spend a lot of time gaming, The PSU is new and of fair quality with 600W/50A available on the +12V rail.

If it is gaming, what titles will the end user be taxing the system with? Depending on that answer, you'll receive suggestions that favor one or two particular cards out of the trio. You also forgot to mention the VRAM on each of the cards.

The PSU is new and of fair quality with 600W/50A available on the +12V rail.
That's advertised information, on the stickered side of the PSU, please pass on the make and model of the unit.

GTX 1070 8GB
RX 5600 6GB (Though the OEM version may be less powerful)
RX 590 8GB

I would vote for the GTX 1070, it is quite power efficient and certainly out performs the RX 590.

Ditto on the 1070, the RX 5600 only has 6GB VRAM which is a bummer, and the RX 590 is a bit of a power hog with lower performance, but has the newer drivers than the 1070. Also look for an RX Vega 56 or Vega 64, they also can be power hungry, but they can be tuned to lower power consumption, and give more performance. You're still looking at only bug fix drivers though, with no new game support added. You could also look for an RTX 2060 8GB. Ideally an RX 6600 would give you the best of all worlds, more performance, ray tracing for new games that require it, low heat and power consumption, and driver support. Barring those, an RX 5700 would also get you driver support, it just wont work on any games that require ray tracing. Do you know what motherboard they are using? It may be able to support a cheap Xeon upgrade which would give them some extra performance.

Thanks. Quick answers for a quick question 👍

You can actually see the performance differences yourself here (bar chart).

A very slight edge to the RX 5600 OEM. Followed by the 1070 and then the 590.

As requested earlier, knowing the actual make/model of your PSU would go a long way toward determining suitability. Details matter.

Funny you should pick that site. That was the first place that showed up on a search, but I didn't know if it was trustworthy. Thanks for pointing it out to me.
The reason I hesitated to accept their rankings, was that they always suggest such low PSU wattages as acceptable. So I was in doubt.

They will list the manufacturer minimum requirement. That could indeed be lower than someone like you or I might recommend.

Update:
For some reason the RX 5600 OEM isn't recognized by the Asrock H270M-ITX/ac board. BIOS? The card is good, it was running on another machine recently before this.

I would think the H270 would be new enough to be compliant. What BIOS version is it on?

Is the system booting in uefi or legacy mode? I believe amd switched everything to uefi with the 5000 series. You may need to enable CSM, or change the boot method to UEFI for it to see it. It also doesn't hurt to do a BIOS update if you haven't done one in a while.
