Specifications:

Above is a quick chart highlighting the details between the new card and the previous high end card, the 3870.  The differences between the RV770 and the RV670 are quite interesting, as the RV770 has 1.45 times the number of transistors, yet it has 2.5 times the number of stream processors, and approximately 2.4 times the processing rate of the RV670.  This would suggest that there have been some serious design changes, probably making the stream processors in the RV770 simpler overall.

Here we can see exactly what Sapphire's plans for future models of the 4850 line.  Not only will we see an overclocked Toxic version, we will also see dual slot 512MB and 1GB models as well.
