lol yeah, well I am at a loss to explain it. It's very odd behaviour. Perhaps it is an interaction between my graphics card and the board at 500+ FSB, perhaps it affects the PCI-E frequency such that its affects the data transmission between the board and card. My P5Q-Deluxe did it too.

Seriously if i made a video of the games when it does it you'd laugh your ass off its so fast. Not 'awesome you have high frame rates' fast, but 'stupidly ridiculous unplayable something is definitely wrong' fast.
