yes, I know a bunch of people who killed their x800pros after weeks or months of modding to x800xt. also bye bye warrenty.
You've popped into every X800 discussion with this same quip, and every time someone had to follow you around to clean up the misinformation.
Flashing the bios doesn't destroy anything.
Overclocking significantly beyond the hardware's capabilities can kill things.
Overclocking without proper cooling can kill things.
Overclocking and overvolting can kill things regardless of cooling.
Flashing the bios
can make certain overclocks unstable; you must retest your max clock after flashing.
I have an X800Pro Vivo for four months now; since day one it's been flashed to an XTPE and has yet to complain. It's played FarCry, Halo, UT2K3, Doom3, NFS:HP2, the original Unreal series, Q3, you name it. It's been powered on for 18+ hours at a time during the hardcore gaming sessions
Use some common sense and you'll be perfectly fine. Don't just assume it will work at XTPE speeds, even if it does, don't assume it will be cool enough there. Start with "stock" clock speeds, start with "stock" pipes, and at least in the beginning, start with "stock" cooling to get an idea of what the normal temperature should be.
