That is a good question...although I'm fairly sure they wouldn't be able to test against retail drivers and hardware...

That's what I don't like about all these "tests" they do...nothing tests like real world application and we, as consumers, definitely don't get to bench with the best of the best...

I mean, hell, I'm up there as far as hardware bleeding edge is concerned, but I'm behind the curve with sites like Tom's hardware, etc...hehehe...
