Wait a damn second here...

To all those who said yes it can...

BULLSHIT.

Driving a car on the freeway can cause your car stereo to fail.

The fact is that ANY video card under a big load can get thermal damage and fail. Multiboxing puts a big load on your system, but if you keep your system maintained, clean and FUNCTIONAL fans, clean airflow, dry conditions, etc, and the system isn't flawed by design (shitty heatsync, etc) then multiboxing wont break shit.
I agree with you. The act of multiboxing won't "break" a graphics card any more than another single heavy graphics-intensive game will. If someone is having problems, it's because either their ambient (room) temperature around the case is too high or the airflow through the case isn't enough. Properly cooled graphics cards are built to withstand thousands of hours running at full load. If a card is acting up, there's a chance it's defective, but I'd bet the ambient or case cooling isn't good enough.
