In the UK currently :

5870 costs 170 GBP and gets 440 mhash/s so about 2.6 mhash/GBP

7970 will cost rougly 430 GBP and get 666 mhash/s so about 1.6 mhash/GBP

Thus, the 5870 is still much better and you can also get a 5970 that gets 850 mhash/s for about 400 GBP.

Power figures ?

7970 is going to be 200 watts I believe, and the 5870 is 188 (both at stock watts). This is where the 7970 suddenly shines. Even if the 7970 is 250 watts, thats still a jump in efficiency.

You think it will be 200 watts w/ a 20% overclock? I wish the OP had a kill-a-watt.

Hey OP do you have a kill-a-watt you could purchase locally. If you are in the states Home Depot and Lowes carry them. If you can find one locally I am sure we could get together the 3 or 4 BTC to get some accurate power readings.
