My rig
5090 with WireView Pro II + 3090 on a Fractal Meshify 2 XL case.
Been upgrading since 2024 and I wish I had bought 2x64gb back then.
The 2x32gb RAM sticks were 209€
Complete specs:
9800X3D
X870E Taichi
64 gb DDR5 30 CL 6000 mhz 32x2
5090 Astral - bought before the price hike in back in 2025
EVGA 3090 I bought used in 2024 from a miner - changed the pads and paste works like a charm.
1200w PSU
+3 NVME SSDs and a 12tb hdd drive, all bought before the price hike.
Running pi / hermes with qwen 3.8 27b at q6 on the 5090 - full context + vision and turboquant with beellama.
If I want to run both GPUs I use qwen 3.8 27b at Q8
Using Cachyos headless most of the time to save up VRAM.
I know my PSU is "short" for these 2 GPUs, at the same time, but the 5090 is power capped to 400w + max 1600 clock - i'm not getting the most out of it but performance is decent for what I need.
The 3090 power capped to 250w + 1400 mhz clock
I can run Deepseek v4 flash IQ3xxs albeit at low PP, 16-20 tk/s, which is a bit painful, so I really don't use it as much as I use Qwen.
When I want speed for more basic stuff, I load up NInfer qwen 3.6 35B, it's insanely stupid on a powercapped 5090 at 300 tk/s average. It's great for really bursty inferance with Hermes, some drafts etc.
