Notes
We're including numbers for high-quality settings at 1,920x1,080 and card-bustin' 2,560x1,600 resolutions. A three-card comparison enables us to use recent drivers from both sides - Catalyst 12.11 beta 11 and GeForce 310.90 - and we've added in Call of Duty: Black Ops II and Far Cry 3. Each title is FRAPS'd during an intensive gameplay section.
Focussing on three cards also provides the opportunity of giving you more meaningful data. Alongside the usual average FPS graphs we're including per-second framerates for both resolutions. This should give you a better idea of just how each card performs.
