Why this build works
Pairing the Ryzen 7 9800X3D with the RTX 5080 gives you smooth 4K gaming with every setting turned up, with DLSS to push frame rates higher still. If you don't need 4K, the RTX 5070 Ti delivers most of the performance for noticeably less.
Going all out
The RTX 5090 is the fastest graphics card available, and the 1000W power supply already meets NVIDIA's recommendation for it.
Before you build
Check the cooler's radiator fits your chosen case's top or front mount, update the BIOS before installing Windows, and make sure the graphics card's 16-pin power cable is pushed fully home.
