AMD has been spitting out new graphics cardslike crazy since launching the Radeon HD 5000 series five months ago, a record eight cards to be precise. With today's release that translates into almost two new graphics cards each month. While not every one of them has left us with a tingly sensation, the series as a whole is very impressive and has allowed them to cover almost every price point in the discrete graphics market.At present, the Radeon HD 5450 kicks things off at around $50, followed by the 5570 at $85. As we move towards the mid-range segment we find the Radeon HD 5670 for $100, which delivers just enough power to outclass Nvidia's lackluster GeForce GT 240. Then things start to get interesting with the Radeon HD 5750 and 5770 graphics cards offering some decent gaming performance for $140 and $165, respectively.
