Budget upgrade for a 31B model? Dual GPUs over PCIe x1 or another approach?

Looking for advice on upgrading my AI server on a budget.

Key points

  • My goal is to run Gemma 4 31B Q5KM (~23GB) at 16K+ context (q8), achieving at least 15 t/s.
  • Currently running the 31B Q5 model at 53% CPU / 47% GPU offloading, which is somewhat useable but slow (in 243, out 2.3 t/s (mtp 2.7)).
  • Add an RTX 5060 Ti 16GB (~$750 new here in Thailand, no used available), move the 3060 to a powered PCIe 3.0 x1 riser, and use layer splitting.
  • --> 2× Tesla P100 16GB (or similar) on a cheap X79/X99 Xeon 32-64gb ddr3 system (~$600–900 total).
