Gigabyte GTX 570 vs Sapphire Radeon 6970 / 6950 vs Radeon 5870 - All Overclocked
 

On our test bench is a GTX 570 from Gigabyte and the Radeon 6970/6950 from Sapphire. We will be overclocking each of these and putting them head to head against each other and an overclocked Radeon 5870 to find out how the new cards compare in this scenario. As always real world gameplay will be used, including Black Ops and HAWX 2 and just for fun we will throw in 3DMark 2011 Professional.
