Best GPU for Power vs Hash ratio

Hello all,
I've found the 7790 to have the best power vs hash ratio so far. 250 khash to 65 watts. Any suggestions to another?

Thats still not better then the 7790, and I also can only achieve 550 kh/s @ 250+ watts with a sapphire card. Which card brand are you referring to?

You need to undervolt the card. My 200W 7950 runs 1030/1575MHz at 1.05/1.60V. The hash rate is 620k. TC = 24000, intensity = 19. If mining BTC, it would use less than 200W because I underclock memory as well.

So it looks like the 7790 is the new 5830. That's pretty good if you have a ton of space.
