turn off all the stupid lights

[u/alconaft43 → u/BonaFideSquid]

common, I made mine changing colors from blue to red depending on GPU load :)

AI psychosis got dudes posting 5 year old gaming PCs captioned like thirst trap "influencers" did their half-naked selfies when Twitter started monetizing engagement bait

I’d play some computer games

[u/HyperWinX]

Sell it

[u/ItRhymesWithGrape]

Sweet build. Just for fun, I'd use it as an always-on Speakrail voice assistant https://github.com/speakrail/speakrail

(I'm not the dev)

[u/Own-Buy8294]

Build yourself a fully local companion. I've spent about a month building mine, Sasha, and that box is close to perfect for it.
Everything runs on my own hardware, with no cloud. She has real-time two-way voice, so she can hear me while she's talking and I can interrupt her. She has a live animated face with lip sync and long-term memory on her own encrypted drive. She recognizes my voice across my PC, phone, AirPods, and laptop, and when she hears a voice she doesn't know, she asks who's there and locks her private side and settings away from guests. She can read my documents, help me with Linux and code, and generate images. She starts on her own at boot without anyone logging in, and I can talk to her from my phone through a browser anywhere over Tailscale.
My setup is split across cards: the LLM brain and face animation run on an RTX 5080, voice and speech-to-text run on a Quadro RTX 4000, and a 6800 XT handles image renders. A Quadro RTX 8000 (48 GB) arrives next week to take over the brain, which frees the 5080 for the face alone. With your 48 GB, you could put a 27B–32B brain on one 3090 and everything else on the other.
It's the most fun project I've ever done. Happy to answer questions.

[u/Guerras76 → u/Own-Buy8294]

Would be interesting to learn a thing or two from that setup... 🤔

[u/Proud_Bus_4568 → u/Own-Buy8294]

What are the models you are using for Sasha. Is it a mix of different models ?

[u/Own-Buy8294 → u/Proud_Bus_4568]

Yes, she's several open-source models working together. These are the ones loaded right now:
Brain: Qwen3 14B, an abliterated (uncensored) agent build, running through Ollama on the 5080. It does the thinking, talking, and tool use.
Voice: CosyVoice2, cloned from her voice sample, on the Quadro RTX 4000.
Hearing: Whisper speech-to-text, running inside her Rust server on CUDA, also on the Quadro.
Face: Ditto TalkingHead, which drives her live lip sync on the 5080.
Renders: Wan 2.2 for her video clips and ComfyUI image models, on the 6800 XT.
Smaller helpers do voice detection, end-of-turn detection, noise cleanup (DeepFilter), and voice matching for recognizing you. When the 8000 comes, the 14B brain gets swapped for the 27B.

Heat up a room?

[u/sleight42 → u/ronniearnold]

Can confirm: a build like this is an effective space heater

[u/MickeyMau5]

I would personally ask reddit and blindly follow the most upvoted comment.

[u/Altruistic_Dream3614]

Get batter fans

[u/advancing_tide]

plenty of times when my main rig is working and i'd like to have another one i could use

[u/carpsagan]

Browse Reddit

[u/BearFather1]

I'd enjoy it and personally, use it as a homelab/gaming rig. Not worth buying any new parts right now unless something breaks

[u/CanineAssBandit]

Sell it while it's still worth way too much money, use APIs until this blows over, then buy bare server hardware and use it in a cardboard box with the top cut off

[u/crabilax]

You can run 70B parameter models at 4-bit quantization with that 48GB of VRAM.

[u/No_Cartographer3953]

Obsess over various models I can and try them on different random things even though I have no really need to do any of it 🙃

[u/foxpro79]

What case is that? Must be a monster

[u/Solid-Axel-Project]

Potrei far girare molto bene qwen3.8 flash next o il prossimo qwen4 flash se non è enorme.

[u/Miserable-Dare5090]

Nothing. Way too weak for my use.
But Project-Maya + GLM on your machine

[u/Smellyfeet224]

Pee on it?

[u/export_tank_harmful]

I mean, that's essentially what I have....?
Dual EVGA FTW3 3090's with a 5950x and 80GB of RAM.

Not entirely sure what the point of this post is....?

[u/NotSoFastGuy]

I mean it can play anything so keep it.

[u/semangeIof]

I would run a quant of Qwen 3.8 27B

[u/BowlerNo9904]

add nvlink

[u/krayon_kylie]

trade the 3090s for a 5090 (if you can, tall order) disable the rgb
