I'm planning a new PC with an AM5 motherboard and DDR5 memory, possibly using a Radeon RX 9070 XT. However, I may receive an RTX 2080 Ti as a gift and am wondering whether it would be compatible with the rest of the build. I'm still learning about PC hardware, so I'd also like to know how much performance I'd be giving up compared with the 9070 XT and whether the 2080 Ti would make sense with a modern AM5 processor.

The 2080 Ti is still a capable card, but it’s considerably older and slower than the RX 9070 XT. If you can afford the 9070 XT, sticking with your original plan will give you noticeably better gaming performance and a more current feature set.
Yes, the RTX 2080 Ti will work perfectly fine with an AM5 and DDR5 system. The graphics card connects through the motherboard’s PCIe slot, so it isn’t tied to the platform’s memory type. Just make sure the power supply has the correct connectors and enough wattage.
Using a 2080 Ti with something like a Ryzen 5 7600X would be reasonable, especially if the card is free. A faster processor such as a Ryzen 7 9800X3D would still work, but pairing it with the older GPU means you wouldn’t get the full benefit of that CPU until you upgrade the graphics card.

The performance gap is substantial—the 9070 XT is roughly around 80% faster in some overall comparisons, although the exact difference depends on the game and settings. The 2080 Ti is closer to the current midrange than to the 9070 XT.
