Auto overclocking does work, it's just too... general? slipshod? I dunno the correct word here, but it's not safe. I would like to see if anyone could flash his/her card with an unlocked BIOS, that would rule. Technically you could just take a sager 7800GTX's BIOS, change the device ID #'s to match those of a Dell 7800GTX, and have at it. It would be insane if this would trick the Dell into accepting the card while enabling FULL software overclocking functionality. Of course, this is banking on the fact that Dell cards are only software (BIOS) locked, and that the flashing wouldn't kill the card due to unforeseen complications. Anyway, something to think about, but I can't kill my new 7800GTX when it comes in as I can't stand this X600 as it is
EDIT: milkman, check the CD for something that says "Original.rom" or something, or clocks at 400/1060, which are the factory clocks.
