Build Notes
Flagship hybrid for buyers who want top-tier 4K gaming and local large-model experiments in one tower. The 32GB Blackwell GPU has more AI headroom than 24GB cards, but 70B-class use requires CPU/offload, tight context settings, and realistic throughput expectations.

Assumptions
- GPU VRAM assumption: 32GB from NVIDIA RTX 5090.
- System RAM: 64GB.
- Ratings assume Q4-style quantization, moderate context, one local model running at a time. Treat them as fit guidance, not a speed estimate.
Llama 3.2 3B Instruct technical details
Family: Meta Llama 3.2
Parameters: 3B
Quantization: Q4_K_M
Approx. model size: 2GB
CPU-only: Possible
VRAM: 0GB min / 4GB recommended
RAM: 8GB min / 16GB recommended
Full GPU offload: Should be possible when memory fits
Context warning: Long documents can still push memory use up, even with a small model.

Quantization: Q4_K_M
Approx. model size: 4.4GB
CPU-only: Not recommended
VRAM: 8GB min / 12GB recommended
RAM: 16GB min / 32GB recommended

Qwen3 8B technical details
Family: Qwen3
Parameters: 8B
Quantization: Q4_K_M
Approx. model size: 5.03GB
CPU-only: Not recommended
VRAM: 8GB min / 12GB recommended

Full GPU offload: Should be possible when memory fits
Context warning: A 32K+ context can be much heavier than a short chat session.
Local AI performance is approximate. Results depend on quantization, context length, backend, drivers, RAM, and whether the model fits fully in VRAM.
Order and handover
Key practical details
After payment or quote request
You receive a confirmation email. We check availability and confirm any practical substitutions before continuing.
Assembly and QA
Planned work includes software, drivers, a GPU/AI smoke test, thermal load sanity check, and memory/storage health checks.
Handover in Estonia
Pickup or local delivery method and timing are agreed after availability is checked.
Warranty and support
Warranty depends on the component, manufacturer, and retailer. Questions continue through the order or quote email thread.
Changes and cancellations
Changes are confirmed in writing; after sourcing or assembly begins, custom-order handling may depend on order state.
Payment security
Card details are entered in Stripe checkout. LLMLab.ee does not collect or store full card numbers.
AI terms in plain language
VRAM
Memory on the graphics card; usually the main limit for local AI model size.
Unified memory
Apple Silicon memory shared by CPU and GPU. Useful for local AI, but not identical to NVIDIA VRAM.
7B / 13B / 70B
A rough model-size signal. Larger numbers usually need more memory and may run slower.
q4 / quantization
A compressed 4-bit model that uses less memory, sometimes with quality or speed tradeoffs.
