The test system was built from scratch, a format of the hard drive was performed (NTFS) and then Windows 7 was installed. Following the completion of the installation, the video drivers were installed. All windows updates were then installed as were the latest builds of the benchmarking tools. Finally, where appropriate the hard drives were de-fragmented. For each test, the video drivers were set to default quality/optimizations (unless otherwise stated).

Good Benchmarking Practice
Where possible, each benchmark was performed three times and the median result for each resolution/setting is shown in the tables that will follow. All applications had their latest patches applied and all hardware features the latest BIOS/Firmware.

Hardware Heaven does not use benchmark scripts. We play the games for long periods of time on various levels and report any unusual findings we see. Then we record with FRAPS across several in game levels recording the averages. This is real world testing and is just how you guys will experience the game. These results give the reader balanced and directly comparable set of figures for comparing cards.

One of the most important aspects of enjoying a game is minimum frame rates which can have the greatest impact on the gaming experience. Due to this we also include a separate graph which details the framerates every second during a level for each of the tested games. This framerate graph allows us to show you how stable the framerates are in on a product and how often they rise towards the maximum or fall to the minimum level. We have also incorporated a 'red line' at the 25 frame per second mark to show the 'cut off' point that most people find acceptable - if you see the current frame rate line drop below this then you can expect the game to become choppy.

Essentially it gives a good representation of the experience you will have when playing. For these tests we focus on a worst case scenario, the most demanding section of game that we can find.

NOTE: As the expanded framerate graph is based on a single run of real world gameplay before we take into account multiple results there can be some variation between identical cards. We make every effort to keep the test as repeatable as possible however with advancements in game technology identical single results are often impossible.
