Gaming performance planning

Pick a game, resolution and settings and see reviewer-measured frame rates for each card. Where no measurement exists we say so instead of inventing a number.

Open the gaming planner

Local AI hardware planning

A model memory calculator that separates weights from KV cache and runtime overhead, tells you whether a model fits in VRAM, and which engines run on your GPU.

Open the AI planner

Guided assembly

Furniture-style step-by-step instructions generated from your parts list, with tools, warnings, common mistakes and a pre-boot checklist.

Preview the guide

Compatibility you can trust

A deterministic rules engine checks socket, chipset and BIOS support, memory type and slots, cooler height and radiator fit, GPU length and power connectors, PSU headroom, M.2 and SATA slots, drive bays and more. Every result is one of four honest states.

  • Compatible

    Verified against structured specs.

  • Warning

    Works, with a trade-off we explain.

  • Incompatible

    Will not fit or will not run.

  • Unverified

    Missing data is never silently a pass.
