You should add the new 7790, a mix between 7770 and 7850.
+1 It's the card with the best price to hashrate ratio and also the best hashrate to watt ratio
Also 7990 would be nice (it's a dual chip 7970)
Edit: The US version works fine, but I had a look at the german version and it shows also complete computers, notebooks and gpu cooling fans. This should be better filtered.
Thanks for checking it out. I cleared out some of the bad data for the other countries, and when it comes up I can clear it out now easily.
For whatever reason it is not picking up the 7990 listings. I will look into this further when I have time.
