That particular series should be idling at 40-45C, and under load 60-75C.

However, I do have a couple questions:

- which 7800GS card do you have? Is is an overclock version (pre-overclocked)?

- is the fan on the card actually working?

- have you tried running the system with the side panel to your case off, and if so, what was the temps like for the card?

- what is the air circulation like in your case? Is there enough air flow?

By all indications, yes, you need to replace the cooler. If you can still find one I recommend the Arctic Cooling NV Silencer 5 (Rev.3) as it will exhaust the hot air out of the case, however since it is no longer in production you will have to do a bit of searching for it. If you can't find that one you could always get the newer Accelero X1.
