I honestly do not see how ramdisks, hyperthreading, and even physX and other like enhancements should be illegal at the bot. I thought the point was performance. If someone can lay a board on a bench, strap a copper pot to it, and pour liquid nitrogen on it for a performance edge, these other technologies should be allowed as well..... Make 'er go as fast as she can!!!!
As long as people aren't photoshopping, all should be good.
Besides, tweaking for the biggest numbers is where the fun is at, and the whole point of overclocking imho.
AS for dual gpu cards.... Give them their own category, everyone wins...
