What Portal Knights actually demands from your PC

Steam's recommended spec for Portal Knights is Graphics: NVIDIA GeForce GTX 970, 4 GB with 12GB RAM and a Intel Core i5-8400, 4.0 GHz. That spec was written for the Digital Bros team's internal "minimum acceptable" target, not for a buyer in 2026 planning to keep this PC for the next four years.

GPU-bound title: Framerate scales directly with GPU power. If you have a fixed budget, prioritise the graphics card and accept a mid-range CPU.

What you can skip vs what matters

Worth spending on: GPU first, then a fast NVMe SSD (most modern games benefit from sub-3000MB/s sustained reads), then RAM at the tier amount.
Worth skipping at this budget: RGB lighting, exotic cooling, brand-name PSUs above 850W (unless you're building enthusiast tier), and motherboards with more than 4 M.2 slots.
Don't compromise on: The PSU. A reliable 750W gold-rated unit will outlast two GPU upgrades.
