Is the 9070 XT a good choice over the 5070 Ti or 5080 for 4K gaming?

The 9070 XT looks like a strong value pick if it's substantially cheaper where you live. The price gap to the 5070 Ti varies, so compare actual listings rather than assuming one card is always the better deal.

Check benchmarks for the games you play, at 4K and with the settings you actually want. A small difference in one set of games doesn't tell you how they'll compare with heavy ray tracing enabled.

For a TV setup, I wouldn't insist on native 4K and every setting maxed out. Upscaling and a few settings tweaks can make a big difference, and 60 fps may be a perfectly good target depending on the game.

FSR can look good, though DLSS may still look better. Check which upscaling options your games support and, if image quality matters a lot to you, look at comparisons for those particular games.

I'd give Nvidia more consideration if ray tracing is a priority and the extra cost fits your budget. The 5080 is worth comparing separately from the 5070 Ti, rather than treating the two as interchangeable alternatives.

Look for 4K tests with the specific ray tracing and upscaling settings you plan to use. That makes the price difference much easier to judge than a general performance average.

For a living room PC, the operating system matters too. Windows can be useful if you want PC Game Pass and games with anti-cheat, while a Linux gaming setup is another option. Check compatibility for your GPU and the games you want before choosing.
