Brand new PC...AMD CPU? (lemm.ee)

Hi again! So...based on my previous post, it'd seem that it's going to be quite some headache to get an old intel 6700 CPU with a PCIe 3.0 to work decently with more up to date GPUs (that is, to see a decent improvement in performance at all). I'd like to do a cross-jump to AMD CPUs this time, to be paired with a 6800XT or a 7800XT. I intend to game on Linux, although there will be a Win10 partition for the troublesome games, and also for the Vive Wireless, which is unsupported on Linux. But I've been out of the AMD loop for a while. What's cooking? What would be a good second-to-last generation CPU recommendation or so? Am I missing any important tech if I don't choose the latest and the greatest? Is ReBAR a thing yet? (Not sure if this is the answer to PS5's direct asset streaming from the SSD straight to the GPU). At this point, I'd like to know what CPUs are adviseable, in order to get some idea for a PC build, so I can go get quotes...and see if that's something I'd be able to afford :)

Ok...So I think I'm mostly thinking of an AM5 board with an 7600 CPU and possibly a 7800XT GPU, 2x16GB DDR5...What should I look for on an AM5 board if it was to last? I mean, I've been using a Gigabyte Z170K3 for nearly 7 years, and so far I never had an issue with it. Then again I never had to mess with it either, other than swapping SSDs and HDDs. Also, what kinda power will I need to hold all this together? Up until now a 750W PSU did the job just fine, but not sure with this config what would be advisable. I'm also concerned as due to the home crappy layout, a lot of stuff goes to the same damn fuse (a NAS, a microPC that acts as self-hosted server stack, a TV and a PS4), so sometimes the fuse gets triggered and shuts everything down. Not great for the PC, but definitely not good for the NAS. This is not all that frequent, maybe once every 6 months...but I don't want to increase it if possible.

The power requirements of AM5 are a lot higher than AM4 but thats usually just a problem on the higher end chips. And compared to Intel's high end they look downright eco-friendly. 5800xt is a beast but looking down the road AM5 is the way to go. The 7600x is a solid CPU and if you get a decent motherboard then you will at the very least get the next generation AMD CPU upgrade path and hopefully the one after that too.

Main thing to look for in a motherboard I think is features, pcie layout, and then vrm quality.

On my current motherboard I was having issues with sata drives not being detected and thought I may have fried something but it turned out that some of the SATA ports were disabled if you used both M.2 slots. I also have to fiddle with the bios to get Linux to boot rather than Windows (I dual boot on separate drives). By default it always boots to Windows after a hard reset.
