the price for HD4850 at launch is very low! It's the same of the GEFORCE 8800GT but RV770 PRO score the same as 9800GTX that have a price of 300+$
In Italy for example geforce 8800gt is priced about 140€ while geforce 9800gtx 230€. The first shop that have radeon hd4850 have a price of 175€.

I hope that the price of hd4870 is lower as 4850, too!
