SAPPHIRE HD6970 BFBC2: Vietnam Special Edition
 

The SAPPHIRE HD6970 BFBC2: Vietnam Special Edition will be competing with NVIDIA's GeForce GTX 570 and NVIDIA's GeForce GTX 580. We overclock the SAPPHIRE HD6970 BFBC2:V Special Edition using SAPPHIRE TriXX Tweak Utility and voltage tweaking to see how it can compare to the more expensive GTX 580.
