the default voltage of HD 6950 is 1.1v and of HD 6970 is 1.17v. I would say if you want stock voltage OC go for for 860 Mhz for 24/7 stability. If you want voltage OC you could go for 1.17 to 1.2v provided you can keep temps under 80c ingames. In that case you can even hit 950 Mhz. I run my XFX HD 6950 at stock voltage at 850 Mhz. I haven't felt the need to do voltage OC. so unless there is a game where you wan't more performance badly just stick to stock voltage OC.
