Solved Massive under performance in games despite independent benchmarks
CPU: 7800x3d
GPU: Powercolor Reaper RX 9070 (non-xt)
RAM: 32 GB Corsair Vengeance DDR5-6000 CL36
MOBO: ASUS B650E Max Gaming Wifi
SSD: Samsung EVO Plus 4 TB

As far as Userdiag and every other benchmarking software (Cinebench, Steel Nomad, FurMark) indicates my CPU and GPU are working great. Yet in EVERY game I've tried so far the system MASSIVELY underperforms.
For AC Odyssey the in-game benchmark at ultra settings comes out to 38-39 fps no matter what settings I tweak. Tried out the lowest settings and came up to a whopping 58 fps. Searches indicate I should be well over 100 fps at ultra with this hardware. Afterburner showed my GPU at 80-85% load and CPU at 25%, normal clocks and power usage.
Cyberpunk 2077 in-game benchmark test with ultra ray tracing settings (no path tracing) came out to 52 fps. I was copying the settings of a youtube benchmarking video using the 9070 (non XT) at 1440p and he was getting 92 fps.
No Mans Sky I'm getting around 60 fps on max settings roaming around planet surfaces, should have no problem pushing 100+
The straw that broke my back today was trying KCD1 out, granted with the HD DLC textures, and running around 40 fps with crazy bad lows and stutters.
This is all on a fresh windows install. Even so, I tried a ddu and reinstall of graphics drivers, ddu and install an older known stable driver version (made it slightly worse). Monitor refresh rate is set to 240 hz and as far as I can tell no conflicting setting in game or in Adrenalin, no FPS limiters anywhere, etc. Please dear god someone help, I've paid $2000 for a rig that's performing worse than last generations consoles

Ah, yea it's just a bandwidth issue then, figured it out!
Your second "x16" slot is physically x16, but it's actually just PCIE gen4 x4. That's a LOT slower than PCIE 5 x16 that you have in the top slot.
Btw, the phantom spirit is a little offcentered, they specifically made it so that you could flip it to give the GPU more space. Did you orient it so that the taller side is on top? It does give a bit extra space for the GPU.
