Finalizing my New Desktop Rig 96GB VRAM + 128GB RAM – 3rd GPU possible in this setup?

Unfortunately now I can't go with Server setups(like Epyc or Threadripper) due to current price of ECC RAM & Processor, Motherboard as well. So below is my planned current setup.

I know that Consumer Desktop setups are not suitable for more GPUs like 4 & above. What I'm expecting is to use 3 GPUs in this setup. Can I expect decent performance with 3 GPUs & without any stability issues?

  • Processor : AMD Ryzen 9 9950X3D2 Dual Edition
  • Motherboard : ASUS ProArt X870E-Creator WIFI
  • GPU : AMD Radeon PRO W7800 48GB - 2 Qty - Total 96GB VRAM
  • RAM : 128GB(2 x 64GB 5600 MT/s)
  • SSD 4TB
  • HDD 20TB
  • PSU 2000-2400W

For 3rd one, I might buy same GPU or NVIDIA 48-96GB in future after price down. (So with 144-192GB VRAM, I can run models up to 400B in future. I'll add additional 128GB RAM too in future.)
