Depending on the mfg, your card may still be under warrenty.
My XFX 9800gt died last year and they gave me a 5770 as it had a lifetime warrenty. It was a lifetime limited warrenty that was upgraded to full lifetime with registration on their site. Check it they may replace it or give you a credit.
Unfortunately it is not under warranty, but thanks for the advice, always worth a look before forking out for a new card.
