It's a good point though, cut-down parts of the same core are usually still within 20-30% of performance
usually less...
if you look at the performance difference between parts of the same core that were launched at the same time, the difference is very small...

with 5870 and 5850 the difference seems to be really small at least it was at launch... i remember that in some benchmarks there was almost no difference between 5850 and 5870...
