FAQ
Common questions about upgrade-gpu.com.
How does the calculator work?
You enter your current GPU. We look up every GPU currently listed on Amazon for your market, calculate the performance gain over your card using a unified Perf Index, and rank them by % gain per CA$100 (higher is better). The best-value option becomes your verdict.
Can I check if my GPU is enough for a specific game or app?
Yes — use "For a game or app" instead of the general upgrade search. Pick a specific title (or the closest category if we don't track yours by name yet) and we'll check whether your current GPU already clears the requirement, and if not, show only upgrades that actually get you there.
What is the Perf Index?
A single number that blends two benchmarks: 3DMark Time Spy (70%) and FP32 throughput in teraflops (30%). Formula:
0.70 × (TimeSpy ÷ 360) + 0.30 × (TFLOPs ÷ 1.65)
Both inputs are from publicly available benchmark databases (3DMark and TechPowerUp). No marketing claims.
What does "% gain per CA$100" mean?
It measures how much faster you get per CA$100 spent. Formula:
(% faster than your current card ÷ listing price) × 100
A score of 18+ is excellent value. 6–18 is reasonable. Under 6 usually means waiting for a price drop or next-gen release is the better call.
How much performance gain is actually noticeable?
Under 25% faster is rarely a step you will feel in day-to-day use, so upgrades below that threshold aren't scored here. 25%+ is a clear step up; 50%+ feels like a generational leap.
What GPU upgrade is worth it for 1440p gaming?
Enter your current GPU, switch to "For a game or app," and pick a 1440p target — the requirement bar and rankings adjust to that resolution automatically. As a rough guide, most current 1440p titles need at least 10–12GB VRAM and a Time Spy score around 14,000+.
How fresh is the price data?
Prices are scraped from Amazon daily. Listings that haven't been seen in 7 days are removed from results. New and used conditions are tracked separately.
Which markets are supported?
Currently US (amazon.com), UK (amazon.co.uk), France (amazon.fr) and Germany (amazon.de). Canada and Australia are in progress.
Why is the UK verdict different from the US for the same GPU?
Verdicts are priced independently per marketplace — Amazon UK and Amazon US carry different listings at different prices, so the best-value pick (and the % gain per £100 vs CA$100) can differ even for the same GPU.
Are the Amazon links affiliate links?
Yes. When you click "Buy on Amazon" and make a purchase, we may earn a small commission at no extra cost to you. This is how the site stays free and independent.
Affiliate commissions do not influence rankings. Cards are ranked purely by performance gain per dollar, and we never promote a listing because it pays more.
Why isn't my GPU in the list?
We track 184+ GPU models. If yours is missing, it's likely because it predates our benchmark database or uses a very uncommon name variant. We add models regularly.
Are used GPU listings included?
Yes, and they're flagged clearly. Used cards are often excellent value; a used RTX 4070 can outperform a new RTX 3080 at a lower price. The condition badge (New / Used) is shown on every listing.
What is a good % gain per CA$100 score?
Over 18 is a steal, 6–18 is reasonable depending on budget, and under 6 means wait for a price drop or next-gen release. These thresholds are what drive the Yes / Maybe / No verdict on every GPU page. They are set in US dollars and converted to each store's currency at fixed exchange rates, so the same real price gets the same verdict in every store.
How do I know if my PSU can handle a new GPU?
Check the recommended power supply wattage on the GPU's product page or manufacturer spec sheet against your current PSU's rated wattage, leaving headroom for the rest of your system. We don't currently factor PSU compatibility into the verdict — treat it as a separate check before buying.
Is the benchmark data accurate?
We source specs from 3DMark's official database and TechPowerUp GPU database. Time Spy is a synthetic rasterization benchmark, which correlates well with gaming performance at 1440p but won't reflect ray tracing or compute-heavy workloads equally. Real-world results always depend on your specific game, resolution, and CPU.
