Calculated hash rate for 7850 is 255mhs on stock clocks.
7870 = 370mhs and both cards worthless as investment like a 79xx series.
I think real hashrate will be identical to calculated values.

I have a feeling 7970 will reign top tog until the dual GPU card comes out. For the 7 series at least.

They look ok I suppose. They won't replace the HD 5830 while there are some still on the market. Curious what the power consumption will be while mining at 1.2 GHz on the core and 300-500 MHz on the ram.

Those benchmarks are worthless, Tom's doesn't know how to bitcoin mine. For example, the 7970 which can do 600mhash with diablominer was doing 330~ on the tom's hardware benchmark. It's that bad.
Based on simple extrapolation I'd bet the 7850 could do 400+ mhash, and 7870 450+ mhash... but this is just a semi-educated guess based on actual performance numbers for the 7970 vs tom's terrible benchmark result.

That should be awesome 
I ordered 2 yesterday, 7870 crossfire, well see what happens 
If you have, what hashes are you getting?
