I'm about to purchase the Sapphire Radeon 6950 2GB 100312-3L from Amazon.com in a few days. Can I toggle the switch to position 2 to unlock the shaders before I power on the computer with it installed or should I have it in the 1/6950 position first before doing the BOIS switch? Read online and it said the 2 switch has the 6970 shaders pre-loaded, from eteknix.com. Can anyone verify this please? Would I also need to install DirectX 11 drivers even though I have the latest version of Catalyst already on my system? Stupid integrated 4290... So, flip switch without turning on computer with card installed to get to 6970 shaders WITHOUT using card whatsoever in 6950 mode. Recommended and any suggestions? EDIT: I also read to uninstall EVERY AMD/ATi driver before flipping the BIOS switch to 6970 shader mode.
