Hey, I just got a 7950 for mining, and I noticed that Powertune kicks in very often, and I have to raise the Powertune limit in order for it to run full tilt at stock clocks. This is a Sapphire 7950 Flex with the Dual X cooler. I haven't done any gaming on it, but that got me thinking - maybe some of the frame latency variations in TR's reviews are because Powertune is kicking in. Did you guys take that into account?
