GPU Upgrade Cost Calculator

Pick the graphics card you own and the one you want. We estimate what selling yours on eBay would net after fees and what the new one costs, using the current asking prices of used listings. Free, no signup, nothing is sent to eBay.

eBay fee (% of sale)

Per-order fee ($)

Defaults are eBay's standard US selling fee, which applies to graphics cards: 13.6% plus $0.40 per order over $10 (eBay's fee page). Edit them if you have an eBay Store or a Top Rated Seller discount. The fee also applies to shipping and tax you collect, which we don't know, so real fees run slightly higher.
