The 4000 series video cards is one of ATI's most successful, and also one of the most wide-ranging. There's the HD 4870 X2 at the top — widely lauded as the current performance graphics champ — followed by the 4870 and 4850. With the HD 4670 at $80 and the HD 4850 at $170, it was logical for ATI to fill the price gap. At $130, the HD 4830 looks to follow in the tradition of its brethren and represent very good value.
