Seems roughly on par, if overclocked, with a 9800XT (which is way overpriced in my opinion) at stock, so it seems like a good value in comparison to a 9800XT. When overclocked, it appears to be ranging from about 10% slower to 20 % faster than a 9800XT at stock, so say 5-10% faster overall.
If you consider most 9800pros overclock to around XT levels, then overclocked it is roughly the same value, maybe a hair better due to a newer feature set, as a 9800 Pro overclocked, which by any standard is a nice value.
If the tweakers uncover 4 or 8 additional pipes with a high degree of modding success and the memory bus isn't handicapped with a 128bit bus or extremely slow ram, this would be a tremendous value IMHO.
