Basic overclocking question

By the time you damaged your card with overclocking
you really don't wanna use it anymore.

Hi all,

I picked up an Albatron Ti4200 128mb card today and want to overclock it a
bit. I tweaked the driver level clock frequencies to 270mhz core and
533mhz
memory and the card seems perfectly stable under D3D games with no
artifacts. My question is, will this cause the card harm in the long term
(stock heatsink/fan)? I plan to hang onto this card for at least a year,
does excess overclocking show itself as system instability or is it likely
to just die unexpectedly after being overclocked for a period of time? I
guess basically I want to know how much overclocking will reduce the life
of
the card.

Cheers,
Matt
