Hey Guys, I have a newb question, which program do you recommend to Overclock 2xHD5850 in Crossfire, and which driver should I use....I know they are a lot of bugs about crossfire and overclocking. Will changing my Bios from beta 0704 to 0802 will help me?

(This is my new Update rig, I add the EK Mobo block and a HD 5850 block, I also used the Triple serial bridge for my VGa Cards and using a Link in the middle of the bridge because I dont have 3 cards)
