I just recently purchased the Visiontek HD3870OC edition from Best Buy. Installed the card and the drivers. The card itself runs fine. But when you load Catalyst Control it states that the card is running at 800core and 1170(2340 effective) memory. Now if memory serves me correctly the core should be at 840, correct? Now here comes the fun part. When you do auto tune with Catalyst Control overdrive, the slider will let you put core to 840 hit accept, the slider stays at 840 but the effective core speed is still at 800. I checked Visiontek forums but its not even in their product list.
