Elephant in room alert.
Afaik, the 7700 has 16 lanes and an impressive list of alleged HB ports, all connected to a lame 4 lane/ 4GB/s chipset.
If so, imo, its not even salable, let alone worthy of consideration as an ongoing platform.
imo also, there is a raid nvme array in keen gamer's future (and each nvme eats 4 lanes). They just dont know it yet.
Ryzen wont manage nvme raid, unless u go 8 lane video to free up 8 lanes (not a bad idea for many), but its a sweet spot where u can get native onboard the mobo; a fast half speed single nvme (an nvme using 4 backwardly compatible slower pcie2 lanes), and a very fast full speed single nvme as well as multiple sata ssdS on the shared 4 lane bandwidth chipset.
If I am right about nvme raid as an asset to gaming, u need a $550us+ 64 lane TR, or a 44 lane $1000us+ I9 intel. Some intels have 28 lanes. Dunno the details.
NB that TR has; free, bootable, bios raid, and often, 3x reputable onboard nvme ports, so they throw in some expensive and powerful kit free with the TR premium. A highpoint 16 lane 4x nvme m.2 prt card is $400us e.g.
windows non bootable soft raid seems well regarded, but dunno the issues.
TR Quad channel memory sounds good too.
I bet $50 samsung's next model ssd, will saturate the 4GB/s nvme pcie link, so our included "free" 3x array as above, could approach 12GB/s. Its a new paradigm. Storage nearly as fast as ram.
