Can someone tell me if the 7900XTX graphics card will work with my AMD motherboard ( A520M S2H )

Thanks.

It'll work, but you'd be seriously hampering your GPU performance by sticking it into a PCIe Gen 3 slot.

You might want to stick with an older GPU or get a B550 or X570 if you want to keep your current CPU and RAM.

I think the 7900s will benefit most from the upper end AM4 and obviously the AM5 MoBos.

Agree with Axeman, it'll work without doubt, but you may not be getting the full potential of the RX 7900 XT. Still, PCIe Gen3 x16 bus bandwidth is not to be scoffed at, it might be hampered IF you go 8K and expect crazy high framerate, but at 1440P, your CPU would most likely be the bottleneck. 4K should be okay as well, but hey, this is an AMD forum, perhaps someone from the GPU tech department can help answer this, I'm also willing to learn.

So, in essence, you might, just might, not get the full potential of the card at 4K at high refresh rate, but I think it'd be still good. Only card that I've read about that might saturate the bus bandwidth is the RTX 4090, so the RX 7900 XTX would be good in that might not be able to fully saturate the PCIe Gen3 x16 bus bandwidth.
