i remember someone said your hashing speed can be calculated by stream processors divided by 4, at best overclock settings.
for stock clocks..10-20% less.
seems about right for my 5770, 5830 and 5850
well that would mean the V9800 would put it right up there with the 5870 mhash. Still its a slightly different kind of card than the V7800. the V7800 is not worht the cost but is pushing a decent 250. So i was wonder if the V9800 might have something that makes it better.
