Question Help with 8K recording/editing build

[GamingCanBeFunYT]

Ok, so I'm completely stumped here. I know a quick Google search would give some info on what I need to video edit 8K footage, but I'm looking for what specs I need to RECORD 8K video directly from my computer. Example, I know Shadowplay/GeForce experience only offers to record in 4K. However, a quick change in the DSR factors to 8K allows me to use OBS to record in 8K. But, the videos that come out almost always stutter and never play smoothly. I can't use NVENC, cuz when I play a PC game in 8K, OBS always outputs errors and fails to record anything. x264 on the other hand, outputs it just fine with stutters here n there along with audio drops. OBS also refuses to output if I record with HEVC. OBS settings are as follows:

x264
Ultrafast preset
VBR
Bit Rate of 60,000 minimum
Custom Buffer Size set to 0 (less demanding encoding)
Output to MP4
FPS set to only 30 for testing

These settings produces really good results, but like I said, the video always stutters here n there along with freezing and audio drops. I need to know exactly what computer specs I need to record 8K footage with OBS as this will be another investment for my online business. My current build is powerful enough to edit 8K (my build is below n I've already edited 8K video before), but not record in 8K, which is rather odd:

X399 Gaming Pro Carbon
2950x 16 core AMD Threadripper
MSI GeForce RTX 2080 Ti Gaming X Trio
32GB (8x4) DDR4 RAM Kingston HyperXFury 2400Mhz
Samsung 860 EVO 4TB SSD
Windows 10 Pro for Workstations
-----------------------------------------------------

Do any of you think I just need more RAM? I find it really odd I can edit 8K footage but not record it directly from my build. I know I don't need SLI/NVlink, cuz I've done that before with a 2nd of the same 2080 Ti and it didn't make a damn. I've tried every setting under the table within OBS and every single output of 8K video skips here n there. I'm pretty sure I need to just upgrade my PC again, but I'm lost on what component I need to upgrade. Any help would be greatly appreciated.

Have you checked RAM and CPU usage in Resource Monitor while recording?

Have you checked RAM and CPU usage in Resource Monitor while recording?

Yea, OBS uses 80% GPU while the game uses only 20% GPU. CPU runs at 30% altogether. It's a PS2 game running at 8K on the PCSX2 emulator. The game runs completely great n fine. The recordings outputted don't...

Memory never goes above 3,000 MB/3GB. The main reason I ask about RAM is cuz I read online that having more RAM is good not because of the increased memory, but because the increased memory gets fed the higher resolution images and back to the CPU/GPU faster. I even read that having at least 128GB of RAM minimum is needed from a site called Puget Systems (https://www.pugetsystems.com/recomm...-Premiere-Pro-CC-143/Hardware-Recommendations ), but I find that rather odd cuz task manager shows my memory never exceeds more than 14GB at any given time no matter what I do including editing and recording. Idk what to set or what to upgrade to achieve what I'm asking :\
