How we chose

Our buying criteria

A prebuilt gaming PC is mostly its graphics card, so we laid the picks out as a ladder from RTX 5060 to RTX 5090, then compared memory, storage, cooling and warranty at each step. Specs and prices come from the makers' and builders' own pages and listings on the update date; we have not benchmarked them. Each pick shows the trade-off you make at that step.

Graphics card: picks run from RTX 5060 (8 GB) to RTX 5090.
Memory: the picks with a stated RAM figure run from 16 GB of DDR5 to 64 GB, so check the spec for each.
Storage: the picks run from 1 TB to 4 TB of SSD storage.
Warranty: three years parts and labour on the OcUK builds, one year on the HP.

How we choose every pick

Your questions, answered

How long is the warranty on a prebuilt gaming PC?

It varies by maker. Overclockers UK covers every OcUK system for three years, parts and labour, while HP gives the OMEN 16L a one-year limited warranty with no on-site repair. Check the terms on the exact model before you buy.

How much graphics memory do the cheaper gaming PCs have?

Expect 8 GB on the entry picks, such as the OcUK Gaming Carbide's RTX 5060. The OcUK Mach 3.2's RTX 5070 steps up to 12 GB, and the RTX 5070 Ti and RTX 5080 picks have 16 GB.

Do I get liquid cooling in a prebuilt PC?

On the higher-end picks, yes: the OcUK Gaming Mach 6 and the OcUK Gaming Domino both use liquid coolers, while the entry OcUK Carbide and the Mach 5G are air-cooled.
