Why does rivatuner hardware moniter shows 495 on geometric and 485 on Shader and ROP?

7800-class cards use multiple internal clockspeeds (which are not always exactly the same). NVIDIA's been a little hazy about it, but it makes overclocking somewhat screwy. See numerous articles on the card's architecture for more details. It could also be that Rivatuner is misreading it.

Unless you're having problems with the card, I wouldn't worry about it.
