I put together a "parts” computer with left over bits and pieces. 5600g + 6950 XT + 64GB slowish RAM on an X470 motherboard. Pretty ridiculous pairing, but mostly works well.
I say mostly because USB was really broken on it, after a million different troubleshooting steps (including full windows re-install, ugh), the only fix was installing a PCIe USB card. Crazy that USB is still broken on Ryzen.
