    Just got my new Lightning Be to replace my old 5870. The Msi came clocked to 1150Mhz at 1,25v vcore.
    Under load of any game my pc will just reboot, no blue screen or nothing. So i was thinking it may be my Psu thats not keeping up with my new parts?

    Psu Thermaltake Toughpower 850W Dont no how good this one is?
    Core I5 @ 4400Mhz
    Sata disks 6 500gb

    Yes it does sound like the powersupply is overloading, I had the same problem with my Toughpower 750W when upgrading to a GTX570.
    I ended up installing a cheapo 600W powersupply and it worked...
