could ATItool kill my PC?

[lynx]

And even it it does break, Guyver will buy you a new one.

but i don't really have much experience so i don't know where the limits are

Of course, but there really is no way of knowing till you cross the line.
One hundred similar cards might survive and yours could explode.
Or vice-versa.

Any time you OC a part you're taking a risk.

wat card is this again?

another thing u should think about is how much of a performance u gain. and to find out, u can bench ur card using software like aquamark or 3dmark

It's not killing your PC, but there are several alternatives to ATITools that are much better. RivaTuner is my clocking program of choice.
