How PartVerdict works
PartVerdict helps you upgrade the PC you already own — without building a whole new parts list. It answers two things: will a new graphics card fit, power and pair with your PC, and what's the best CPU you can drop into your existing motherboard. No sign-up, runs entirely in your browser.
The five checks
- Fit — card length and thickness vs your case's clearance.
- Power — PSU wattage vs the card's real-world draw, with headroom.
- Connectors — whether your PSU actually has the cables the card needs (the #1 cause of returns).
- Bottleneck — whether your CPU can keep up at your resolution.
- Interface — PCIe generation & Resizable BAR (matters for x8 cards on older boards and Intel Arc).
The performance index
Every GPU and CPU has a 0–100 gaming score on one shared scale, anchored at RTX 5090 = 100. GPU scores reflect measured 1440p rasterization performance and CPU scores measured 1080p gaming performance, cross-checked across multiple sources. The bottleneck check compares the two, so a balanced pairing sits near a 1:1 ratio. Older parts use consistent estimates.
Where the data comes from
Every value is cross-checked across multiple trusted sources rather than taken from a single one, then verified before it ships — the physical specs (TDP, length, connectors, PSU), the performance scores, and the case clearances alike.
We currently track 104 GPUs, 104 CPUs and 66 cases, from the latest RTX 50 / RX 9000 back about ten years.
Honest limitations
Card length varies between board partners, so we store a representative value — you can always enter your exact case length manually. Performance scores are a gaming index, not a promise of specific frame rates. Always confirm the exact card length and your PSU connectors against the product page before buying. This is guidance to help you buy the right card the first time.
