Right, I now have an Accelero S1 rev2 on my card and it is begging to be overclocked further (850/1000Mhz currently). I have emailed Gigabyte asking for an unlocked BIOS and one that gives 1.3V in 3d mode, but haven't heard back, so I may go with the unlocked Sapphire 3850 one unless anyone has a better ideas?
