My 2023 Radeon 7900 XT has started showing serious display problems, and I'm currently relying on the integrated graphics from my Ryzen 7 7800X3D. I game on a 4K and ultrawide setup, so I need a replacement fairly soon if the card is actually dying.
The problem began during a Phasmophobia session when a black bar appeared on one display. Reconnecting the monitor briefly restored the splash screen, but Windows then showed a black area where the desktop should be, with windows leaving ghost images behind them. After restarting, everything worked for about fifteen minutes before failing again. Windows appeared to disable the GPU, and later the display was almost completely dark with a faint red version of the desktop visible.
The system seems to be working again after being powered off overnight, but I'm not confident the card is healthy. I've also checked the system for malware and am running a Bitdefender scan.
My main choices are an AMD Radeon 9070 or an Nvidia RTX 5080. I'm hesitant to buy another AMD card because of the driver issues I experienced with the 7900 XT, but the 9070 would cost much less and be available much sooner. The 5080 would require spending over $1,000 and waiting several additional months, but it should offer considerably better 4K ultrawide performance.
My system has a Ryzen 7 7800X3D, Gigabyte X670 Aorus Elite AX motherboard, 64 GB of DDR5-5600 memory, two Samsung SSDs, and a 420 mm Arctic liquid cooler. Should I troubleshoot or repair the 7900 XT first, and if it is truly dead, is the 5080 worth the extra money over the 9070 for 4K ultrawide gaming?

For your stated use, the 5080 is the stronger 4K ultrawide option, but whether it is worth the premium is personal. The 9070 should be a good value choice if you are willing to use upscaling or reduce settings, especially at regular 1440p. At 4K ultrawide, though, the extra performance and feature support of the 5080 will give you more headroom. I would not wait months without a working gaming PC just to buy the most expensive option unless that price genuinely fits your budget.
Before buying anything, confirm that the GPU is actually failing. The symptoms could be a driver crash, overheating, a bad cable or port, a monitor issue, or a power problem rather than permanent hardware damage. Try another display cable and port, test one monitor at a time, reinstall the graphics driver cleanly, and check temperatures and hotspot readings. Cleaning dust from the card and checking whether the cooler is making proper contact may also help. If the card still produces artifacts or gets disabled under load after those tests, have a repair shop test it before selling or replacing it.
You may want to consider the 9070 XT or RTX 5070 Ti as middle-ground options. The 5080 is faster, particularly with ray tracing and Nvidia’s upscaling features, but its price premium can be difficult to justify. The 9070-series cards generally offer much better performance per dollar, and a 9070 XT can handle 4K reasonably well with sensible settings and upscaling. Just keep in mind that ultrawide 4K is more demanding than standard 4K.
If the 7900 XT is still under warranty, use that route before spending money on a replacement. A graphics card should not automatically be considered dead after a few years, and the black bars, ghosting, red tint, and device disabling could point to a connection, driver, memory, or thermal issue. Test the card in another system if possible, or have a shop run a stress test and inspect it. If it passes, you may only need to fix the underlying display or software problem.
