Sapphire HD7950 Overlock Edition Crossfire Review

Before sharing our closing thoughts, we decided to test the system by slotting in another reference HD7950 and overclocking it to the same speeds as the Sapphire HD7950 cards.

After reinstalling the driver, Catalyst Control Center detected the extra card without a hitch.

All cards were configured to 900mhz core and 1250mhz via the GDDR5 memory.

Adding a third card increases the score from 12,976 points to 16,804 points, an increase of 3,828 points. By comparison, the two Sapphire HD7950's when manually overclocked to over 1,200mhz on the core score 15,406 points …. only 1398 points less than three at 900mhz.
