Wait, it will perform the same as the 4890, but at a slightly lower price point? That doesnt make any sense. The 5770 performs kinda close to the 4890 spec wise, the only difference is the 128-bit mem bus vs 256-bit. The 5770 is about $170 and the 4890 is $199. How can this fit within that $29 price range? This really should perform better than the 4890 by a little bit and be around the $225 area if they want to fit it some place in between the current gen
