Today marks the official release of the HD 4670 and the HD 4650 into the sub-$100 category which was up until now the sole domain of the Nvidia 9500 GT and before it the 8600-series. These cards are not for those of us who want the best of the best; they are for people who want a card to be a jack of all trades which can play games at lower resolutions while offering kick-ass HD video decoding.
