Yeah, it would definitely be interesting to know. I know that 5870 vs 5850 is a bit of an apples to oranges, maybe more like granny smith to red delicious

Anyway, I'm pretty sure this is not a fluke but a lot of people don't look at this kind of stuff. It is puzzling though as it definitely behaves as though voltage scales with core clock and more volts is certainly not always better despite the cooling. It's like the cards have certain voltage "sweet spots" for a given clock. I'm still waiting on my second HD 5850 to test this theory out on as well.
