Perf vs. Price

Your card Upgrade options Best value
Methodology
Updated daily

Perf Index: what it means

A unified score. Blends 3DMark Time Spy (70%) and FP32 throughput (30%). Formula: 0.70 × (TimeSpy ÷ 360) + 0.30 × (TFLOPs ÷ 1.65). Higher = faster.

% gain per $100: the only number that matters

(% faster than your card ÷ price) × 100. Over 25 is a steal, 8–25 is fair, under 8; wait for next-gen or a discount.

Pricing

Scraped daily from Amazon UK. New and used cards are flagged. Prices include delivery where applicable.

Caveats

Time Spy is synthetic: real-world gains depend on resolution and CPU bottleneck. We assume your PSU and CPU can handle the upgrade.
