Looking to reduce the bottleneck for my GPU

Kunaan

I am looking to upgrade my current motherboard and CPU to minimize the bottleneck my GPU is experiencing.

I am currently running an Asus Z170 Pro Gaming mobo with i5-6400 CPU, 64 Gb DDR4 RAM. I would like to keep this as budget friendly as I can as this is used for casual to moderate gaming -- in other words, I do not need top tier parts.

The GPU I plan on installing is a Radeon 6600XT OC. I know the PCIe 3.0 on the Z170 Board is the major bottleneck, but I think virtually any newer board should have the PCIe 4.0. What CPU/Mobo combo would be the best bang for my buck? Bonus points for an ARGB or RGB header. Everything is liquid cooled and I am using an 800W PSUP so cooling and power is not a major concern either.

PCie 3.0 vs 4.0 isn't really an issue: https://www.pugetsystems.com/labs/articles/pci-express-4-0-vs-3-0-video-card-performance-1982/

Sounds like you just need a good CPU/board combo. You'll get PCIe 4.0 anyways, at least enough lanes for your GPU and an NVME drive. Stay away from AM5 now so you can use your RAM, platform is DDR5 only. What's your budget?
