You're the first one I've heard of running those clocks. That's an impressive OC.
Care to share your Vantage GPU score @ that setting?
If you don't own WiC and the mood strikes you, perhaps you could download the demo and run the built in bench at very high quality stock and overclocked.
I am definitely curious about how much of a boost it would get moving from stock to your OC.

Also When ATI tool catches up it will be possible to increase the VC through software, something nvidia has never done.
Another thing worth noting is the fact that the HD 4870 does not have proper drivers yet as its using drivers that were not even intended for the card, just wait until actual 4870 drivers come out, I expect a nice performance jump.
