How to Budget a PC Build
The most important rule in PC building: spend 35–40% of your total budget on the GPU for a gaming build. The GPU determines your frame rate ceiling more than any other component. Once you have a GPU target, work backwards — the CPU needs to be fast enough not to bottleneck it, and everything else (RAM, storage, case, PSU) fills the remaining budget. Use our CPU & GPU Bottleneck Calculator to verify your pairing before finalising your components.
Workstation and streaming builds follow a different rule: the CPU gets proportionally more budget because multi-core throughput and encoding performance drive productivity. A content creator on a $1,500 budget should spend more on a 12-core CPU than a gaming-biased build would, and proportionally less on the GPU. The splits in this calculator adjust automatically based on your selected use case.

PC Build Budget Tier Guide
Each tier represents a meaningful jump in capability. Here is what to expect at each price point in 2026:
| Tier | Budget | Gaming Target | GPU Class |
|---|---|---|---|
| Budget | Under $700 | 1080p 60–144 fps | RTX 4060 / RX 7600 |
| Mid-range | $700–$1,199 | 1080p high-refresh or 1440p 60+ | RTX 4070 / RX 7800 XT |
| High-end | $1,200–$2,499 | 1440p 165+ fps or entry 4K | RTX 4080 / RX 7900 XT |
| Enthusiast | $2,500+ | 4K 120+ fps or maximum 1440p | RTX 5090 / RTX 4090 |

Platform Choice: AM5 vs Intel in 2026
AMD AM5 (Ryzen 7000/9000) is the recommended platform for new builds in 2026. It supports DDR5, PCIe 5.0 M.2, and AMD has committed to AM5 support through at least 2027 — meaning your motherboard survives one more CPU generation upgrade. The B650 chipset is the sweet spot: PCIe 5.0 M.2 support, DDR5, and most Ryzen 7000/9000 features without the X670E price premium.
Intel LGA1851 (Arrow Lake / Core Ultra 200) is competitive in productivity workloads and strong in streaming tasks, but lags the Ryzen 7800X3D in gaming at 1080p and 1440p. If gaming is your primary workload, AM5 with a 3D V-Cache CPU is the better choice; for mixed workloads, Intel Core Ultra 7 265K is a compelling alternative. Reference benchmarks at PassMark CPU Benchmark and per-game data from TechPowerUp.
AM4 (Ryzen 5000) is end-of-life — no new CPUs will be released — but remains an excellent value platform for budget builds under $600. DDR4 costs 40–50% less than DDR5, and the Ryzen 5 5600 + RTX 4060 is the proven budget gaming sweet spot.
Never Underspend on the PSU
The PSU is the one component where cutting corners can damage everything else. A low-quality PSU with poor voltage regulation can cause random crashes, throttle the GPU under peak load, and in rare cases destroy connected hardware through voltage spikes. The minimum recommended spend is $60–$80 for a 650W 80 Plus Gold unit from a reputable brand (Seasonic, Corsair, be quiet!, EVGA).
Use our PSU Wattage Calculator to size your PSU exactly — it accounts for GPU transient power spikes (which can reach 2–3× rated TDP on RTX 4000/5000 cards) and recommends ATX 3.0 where necessary. Never buy a PSU with less than 20% headroom above your system's peak draw.

Frequently Asked Questions
How much should I spend on a GPU?
For gaming builds, allocate 35–40% of your total budget to the GPU. It has the largest single impact on frame rates. At $1,000 total, that's $350–$400 for the GPU — landing you squarely in RTX 4070 territory. For workstation or streaming builds, drop this to 27–33% and redistribute to CPU and RAM, where those workloads benefit more.
Is it worth buying used PC parts?
Yes, with caveats. Used GPUs, CPUs, and RAM are typically safe — they either work or they don't. Avoid used PSUs (capacitor degradation is invisible) and used SSDs with high write counts (check with CrystalDiskInfo). The GPU is where used parts offer the most savings — a used RTX 3080 often costs the same as a new RTX 4060 Ti but significantly outperforms it. Check the GPU Upgrade Worth It calculator to evaluate cost-per-frame on both options.
Should I buy all parts at once or upgrade over time?
Buy all at once if possible. Partial builds often mean compromising on one component to afford another, and mismatched tiers (e.g., an i3 with an RTX 4090) waste money. If you must phase the build, prioritise the GPU and CPU first — they set the performance ceiling. A slower SSD or less RAM can be upgraded cheaply later; changing GPU or CPU means reselling and reborrowing the price difference.
How much RAM do I need for gaming in 2026?
32 GB is the 2026 standard for gaming. Games like Hogwarts Legacy, Star Wars Outlaws, and Microsoft Flight Simulator regularly consume 16–20 GB when running alongside a browser or Discord. 16 GB remains playable but leaves no headroom. 64 GB is only necessary for workstation workloads (video editing, 3D rendering, large datasets). Pair this with 6000 MT/s speed on AMD AM5 — the Ryzen memory controller peaks at DDR5-6000 for gaming performance.
Can I build a gaming PC for under $500?
Yes. A $500 build targeting 1080p 60fps is very achievable in 2026 using AM4 (Ryzen 5000) platform with a used Ryzen 5 5600, a B550 motherboard, 16 GB DDR4, and an RTX 4060 or RX 7600. The AM4 platform (DDR4) keeps costs low compared to AM5. Manage expectations: 1080p at medium–high settings in modern titles is the realistic target at this tier. Check the FPS Calculator for frame rate estimates at your chosen settings.
