I've been digging through some of the Arch and Gentoo documentation trying to get a handle on which of the older Radeon cards use the drivers built into the kernel. While they do a good job about telling me chipsets and GCN architecture, I'm still struggling to find a card.
The Optiplex 9020 I own uses a PCIe x16 slot, first generation or possible second. I've been using the integrated Intel for now but would like to add a discrete GPU. If I'm reading the Arch and Gentoo docs correctly most of the cards seem to be more gaming oriented and require a connection to the PSU.
Ideally I'm looking for a card that does not require a connection to the PSU is 2 or 4GB and can support a 4K monitor.
Any advice would be greatly appreciated.
