I'm using a Radeon 9070 XT with a 270K Plus processor and currently sticking with the stock graphics drivers because newer releases have been unstable for me. My main display runs at 4K, while my other monitors are 1080p and 1440p. Whenever I play a game on the main screen and watch a video fullscreen on another monitor, the game or video stutters several times per minute. Is there a software or display-setting fix I should try, or would adding a separate PCIe-powered GPU for the secondary monitors help?

Start with a clean driver installation using DDU, then install a known-stable driver version rather than assuming the default driver is best. It’s also worth toggling browser hardware acceleration off and back on, since video decoding and GPU rendering can sometimes conflict while gaming.
Check the refresh-rate combination. One person fixed an identical issue by changing a secondary display from 60 Hz to 165 Hz so it matched the main monitor. Try matching refresh rates where possible, or temporarily disconnecting the other monitors to identify whether a particular display or refresh-rate mix is triggering the stutter.
Before buying another graphics card, connect the secondary monitor to the motherboard video output if your processor supports integrated graphics. That can help determine whether the 9070 XT is struggling with the mixed gaming-and-video workload, although the GPU choice itself probably isn’t automatically the problem.
Test the browser and video settings systematically: disable or enable hardware acceleration, try another browser, and switch the video encoder if the player allows it. Also check your memory speed and timings, because unstable or incorrectly configured RAM can show up as intermittent stuttering.
