Yes, that seems like a dying card to me. If it is a bad solder connection somewhere you can try a little ''reflow'' with a heatgun or in the oven. What do you have to loose?
Most times it will not cure forever but if you're lucky you can use it a little longer, sometimes months. Just keep it cool afterwards.
If it is a bad memory chip it is probably game over (very few people can replace these i guess). As a very LAST resort you can try something like an overvolting mod, maybe that kicks it back to life.
Tip for using 9700/9800 cards in the future: do not overclock them and cool them well. The cards that live the longest are cooled with good zalman coolers or the bigger alternatives like the ones from Artctic Cooling. A lot of the cards wit stock coolers are defective or gone. The same goes for every other highend card if you want to get the most use out of it.
