I'm replacing my 2016 desktop, which currently has a fourth-generation i7, a GTX 1080, and 8GB of RAM. I'll keep the old machine as a backup and build a completely new system. There isn't really a strict budget, but I'm skipping the RTX 5090 because its price is several times higher than the RTX 5080. I can purchase a new RTX 5080 for about โ‚ฌ1,100 and plan to play at 1440p and 144Hz on an ultrawide monitor. What CPU and supporting components would pair well with the 5080 without limiting its performance?

The 9800X3D would be the straightforward choice for a top-end gaming build. If you also plan to do productivity work and want to reduce the cost somewhat, an Intel Core Ultra 7 270K could be worth considering, although the 9800X3D is the stronger gaming-focused option.

MellowPine42: I canโ€™t justify spending โ‚ฌ4,000โ€“โ‚ฌ5,000 on an RTX 5090, but Iโ€™m comfortable paying more for the other components if that helps me get the best performance from the RTX 5080.

The Ryzen 7 9800X3D is an excellent match. Its strong gaming performance and large 3D V-Cache make it especially suitable for high-refresh-rate gaming, and it should let the RTX 5080 perform very well at 1440p.
