Is overclocking your graphics card bad for the card, or the computer?

[Waverly]

I recently bought a new game The witcher, now my computer is old but not that old. My graphics card is an WinFast A6600 GT , how much should i overclock it so it runs smoothly, or even runs at all (because it wont run for longer than 30 mins due to the low virtual memory) also any tips or links to overclocking would help. Cheers mate.

Overclocking your card will not help you, and it doesnt oc that well the A6600 GT.
Youre limited in every possible way, starting from the cpu and the gpu slot (i suppose is agp 8x?).
As for the virtual memory, try to upgrade your system ram. I think that 2GB should be fair enough.
