| **Role** | Docker host, OmniRoute LLM proxy, always-on server. 15.5GB RAM. GPU: GTX 760 (dead — see below).
| **Key services** | Open WebUI v0.11.0 `:3000` (NixOS native, not Docker) |
#### GPU upgrade — dead GTX 760 → AMD RX 6600 (recommended)
**Status (2026-08-25):** GTX 760 (Kepler, PCI `10de:11c2`) no longer works. `nvidiaPackages.stable` dropped Kepler support after driver branch 470; dmesg shows `NVRM: does not include the required GPU ... probe failed (-1)`. The legacy 470 driver is EOL and very unlikely to build on kernel 6.18 (~10–25% odds even with kernel pinning).
**Recommended replacement: AMD RX 6600** (~$180–210 USD)
- **Zero NixOS driver pain:** in-kernel `amdgpu` — config becomes just `services.xserver.videoDrivers = [ "amdgpu" ];`. No legacy branches, no kernel-version roulette, ever.
- **No PSU gamble:** many models need no PCIe power connector (132 W). Safe with the new PSU regardless of wattage headroom.
- ~6–8× faster than the GTX 760; pairs cleanly with the Ryzen 5 5600. Flawless KDE/Wayland support.
- Alternatives if a spare 8-pin + ≥450 W PSU confirmed: RX 7600 (~$250), RTX 3060 12GB (~$270, only if CUDA needed).
**Swap procedure (safe):** power off → swap card → boot. If display fails, SSH recovery path is proven (`sam@192.168.20.27 → .13`); previous NixOS generations remain bootable from the boot menu. Update `videoDrivers` to `amdgpu`, then `nixos-rebuild switch`.

Combo `default-opencode-go-ds-flash` prioritises OpenCode-Go before falling through OpenRouter → DeepSeek direct → Google Gemini. See [[Pi Agent Extensions & Skills#OmniRoute — LLM Provider Router]] |
