ATI RV670 has close to R600 performance
 

Our well informed sources have said that RV670 mainstream chip will be as fast as some high end chips but it will be priced in the mid range. It won’t cost more than $200 per card, but the performance itself might be as good as the R600.

To be realistic we expect that R600 will be a bit faster than the upcoming 55 nanometre chip, but RV670 will certainly be smaller, cheaper to produce and most importantly not as hot as the previous chip.
