FPS calculator and PC builder

Know your frame rate before you buy

Pick a CPU and graphics card to see the FPS to expect in popular games, then build around them. Parts that will not fit are filtered out, and every price is in pounds with VAT included.

Start with the first step.

Start from a template

How many frames will your PC manage?

Tell us what is in your PC. You get expected FPS in popular games, a bottleneck reading at each resolution, and a check on whether your RAM and PSU wattage are up to the job.

What you find out before spending a penny

FPS at three resolutions

Choose a pairing and read off the frame rate to expect in popular games at 1080p, 1440p and 4K, and whether the processor is holding the card back.

Whether it all fits together

Socket, memory type, case clearance and PSU wattage are checked as you go, so a part that would not work is never offered.

Which shop is cheapest

Each part is priced in pounds across the shops we track for the UK, GamingKit and CCL among them, and refreshed at least twice a day.

From first pick to the basket

  1. Start with the CPU and graphics card

    They decide your frame rate, so choose those first and the options for everything else narrow to suit.

  2. Let the build check itself

    Power draw is added up and each new part is tested against the ones already chosen.

  3. Order from the cheapest shop

    You leave with a parts list and a link to whichever shop has each item for the fewest pounds.

Common questions

How accurate is the FPS calculator?

Treat its figures as estimates, not measured benchmarks. A single performance model, calibrated against published results at 1080p, 1440p and 4K, works out the average FPS for a processor and graphics card in popular games on high settings, and shows whether the processor holds the card back.

Do the prices include VAT?

Yes. Prices are in pounds and include VAT. They come from the shops' product feeds and are refreshed at least twice a day, so each one is correct as of its last update, and the page at the shop has the final word.

Could I still end up with parts that do not work together?

The configurator is built to stop that. Before a part is offered it checks the CPU socket, the memory type, what fits in the case, cooler height and PSU wattage, and anything incompatible is held back.

What does it cost, and who pays for the site?

You pay nothing to use it. The site earns from the shops when customers reach them through us.
