Guide prices are approximate UK street prices last checked August 29, 2026 (GPU and 32GB RAM rows rechecked September 26, 2026) — not live quotes. RAM and GPU pricing moved weekly through 2025-26; use the per-part buttons to verify current figures before ordering.
CPU
AMD Ryzen 7 9800X3D
≈ £430~$581A gaming-focused CPU choice for this list; compare the 9800X3D, 9850X3D, and 9950X3D in dated independent tests before treating core count as a gaming conclusion. Street for 9850X3D is on the CPU hub, not invented here.

Arctic Liquid Freezer III 360
≈ £95~$128At this budget the AIO is bought for sustained quiet under all-core loads, not because the CPU needs it.

64GB (2×32GB) DDR5-6000 CL30
≈ £650~$878Games will not use it; capture and creation apps benefit from 64GB. Local LLM inference is still limited by GPU VRAM — see the GPU guide, not system RAM alone.

WD Black SN850X 4TB
≈ £460~$6214TB ends the install-juggling that 100GB-plus games create; PCIe 5.0 drives cost more for gains games do not show.

NVIDIA GeForce RTX 5080 16GB
≈ £1,180~$1,593Selected for a specification-led 4K target with DLSS available as a fallback. The RTX 5090 is a higher-cost alternative; compare current pricing and dated tests.

Corsair RM1000e 1000W Gold

Approximate tier total
This list has a specification-led 4K target with DLSS available as a fallback. The RTX 5080 is the selected fit on paper; compare current game performance, thermals, and pricing in dated independent tests. A higher-tier GPU can change the total substantially.
The CPU and 360mm cooler are selected for the stated gaming and creation-workload brief. Compare the 9800X3D, 9850X3D, and 9950X3D with dated tests — 9850X3D is the current 2026 X3D option when you want that step-up; see the CPU hub rather than an invented street figure here — and validate noise and temperatures for the exact case and fan curve.
The headroom choices are the usable specifications: 64GB of RAM, 4TB of storage, and a 1000W ATX 3.1 PSU. For local models, GPU VRAM is the hard ceiling — system RAM helps with context and tooling around the model, not replacing a larger card.
An RTX 5090 can materially change the total at this budget. Guide prices are approximate and the GPU is the most volatile line by far; compare current figures and dated independent tests before ordering. Guide prices checked August 29, 2026; GPU and 32GB RAM rows rechecked September 26, 2026. USD figures are indicative conversions at a static rate, not live prices.
