Sapphire HD 5770 Flex Edition review

A 5770 with four EyeFinity connectors

We've tested five HD 5770s from the leading manufacturers against each other to see which hits the price/performance sweetspot when it comes to mid-range and high-end gaming. We also cranked the settings up (HDR, Anti-Aliasing, reflections etc) even at middling resolutions, to see just how capable these cards really are.

We then tested each card using the following games and settings:

Heaven 2.1
1900x1200, 8XAA, 16XAS, Extreme Tessalation

Just Cause 2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings

Far Cry 2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings

DiRT2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings
