   Kinda hard to decide whether I should go with a slightly older x670e board or go with x870

     @mikoto Aren't there PCIe M.2 riser cards?

     The newer stuff has wifi 7 and usb4 which I don't need ATM but it is kinda nice to have those around in case I ever get a new device that supports those
     
     But on the other hand, the x670e stuff tends to have more usb and m.2 slots which are more useful right now so...

     @mikoto I thought dedicated lanes were one of the motivations for moving away from old PCI to PCIe. :blobfoxgoogly:

     @tk yeah, I even have one in my current system
     
     Main problem really is the PCIe lane splitting situation with some boards, there are some that share lanes with the GPU slot so if I use an m.2 in some cases that reduces the bandwidth available to the gpu

     @mikoto We get it. Threadrippers are expensive. You don't need to feel bad. :blobfoxpatsad: (:blobfoxgooglytrash:)

     @tk yeah, main issue is that mainstream desktop platforms like am4 and am5 only have like 20-24 pcie lanes. Most graphics cards use 16 of those lanes, and then each m.2 SSD will use 4 lanes each.
     
     Boards with more than 2 m.2 slots can either use additional PCIe lanes from the chipset or take some lanes from the GPU. But since the number of PCIe lanes per device has to be a power of 2, it means the graphics card will end up with only 8 lanes
     
     Whether that matters or not really depends on what you want to do. Gaming wise going to 8 lanes of PCIe 4.0 might not be a big deal. Not sure about how much it would affect AI stuff though

     @tk I just want a middle ground between consumer platforms and the workstation stuff, with say 32 lanes for instance
