Is it worth upgrading?
A newer card winning every row of a comparison table does not make it worth buying. This works out how much faster it actually is at your resolution, what that improvement costs per percentage point, and whether a cheaper card would get you most of the way there.
Both cards have to be ones CompareYourGPU tracks. The database currently covers current and recent desktop cards, so if you are coming from something older it may not be listed yet. See what is covered.
