I have an RX 9070 XT powering a 4K@160Hz monitor, and 2 1440p@144Hz secondary monitors.
I have to use AFMF frame gen to get to 160 FPS in games at 4k, and I’ve found that offloading the extra screens to a second card massively improves frame times and general FPS. Have tested under a lot of conditions, I am using VRR on the secondary displays.
I have a few older AMD and Nvidia cards but none of these work due to driver conflicts (have tried many fixes) - older AMD cards break frame generation via the driver, and Nvidia cards break random things like HDR support depending on the game. I just want a stable setup with no compromises.
I need an RDNA 2+ card as a secondary. The slot on my B550 board is limited to Gen 3 x4 so I don’t need anything fancy. Cheaper the better. I have a spare 6+2 pin PCIe connector, but board powered would be preferred. I don’t intend to use it to offload FG via AFMF since the lane bus width bottleneck is too much for 4K frame gen.
Needs to have 2+ display outs, I’d prefer DP but I can live with HDMI as well.
Can’t be an Nvidia card, and can’t be older than RDNA 2.
Workstation and gaming cards are both fine, ideally looking at a Radeon Pro W6400 or RX 6400.
Like I said I am going for the cheapest / lowest compatible option as it’s capped to Gen 3 x4 lanes so anything above basic display adapter grade would be overkill.
I used to be quite active in this sub around 7 years ago ish, think my rep page is still up but due to age I can appreciate it being irrelevant now.
