Gaming PC built around a 4080 Super

Wanting a pc for gaming again. Figured basing it around a 4080 Super would be a good way to get me going until the new 5090's are out later next year.

It's been about 10 years since ive gamed on PC so not really sure where to start with the rest.

Play mostly FPS, COD Battlefield etc but want to play Cyberpunk and Alan Wake at a decent level too.

To be honest if it comes close to something I can buy ready made from somewhere I'm ok with that too if there's any recommendations of where is good.

Already have an OLED screen.

Thanks
