Does anyone have experience with dual graphics cards in their personal computer? What PC games or console do you like to play?

I've run both Crossfire and SLI. Honestly these days multi gpu setups are not widely supported by game developers and Nvidia pretty much dumped it on their low and midrange cards. As for gaming I'd probably recommend Microsoft's Xbox ultimate service, you get a wide range of PC and console games to play for under $20 a month.

You may struggle to find anyone that into gaming. I have a single 3060 that I bought intending to use it for games but I've only ever used it to crack passwords so far.

AMD has a multiple GPU setting that allows the second card to slave off the master. I guess the way it works is the picture is drawn by alternating output from each graphics card. Pretty cool but wasnt sure I had enough junk in the trunk of my power supply. I might try Tomb Raider or Crysis to see how well it runs. Btw feel free to mention some games pc or console that ya like to play.
