Sapphire HD7990 QuadFireX Review

For this review today we are using the latest beta versions of the Catalyst Drivers from AMD and Forceware drivers from NVIDIA. (ForceWare 314.22 and the latest Catalyst 13.5 Beta from AMD).

We built a very high end liquid cooled Core i7 3960x system and overclocked it to 4.4ghz. We paired it up with 16GB of 2,400mhz memory and an ASUS Rampage IV Extreme motherboard.

We wanted to use the best graphics cards on the market today, so opted for the Gigabyte GTX690 and Gigabyte GTX Titan. We don't have pairings of these cards unfortunately for SLi tests, but we include the results in single formation.

All the latest BIOS updates and drivers are used during testing. We perform generally under real world conditions, meaning KitGuru tests games across five closely matched runs and then average out the results to get an accurate median figure. If we use scripted benchmarks, they are mentioned on the relevant page.
