This week AMD has announced a slew of new options to address this market including the Radeon HD 6670, HD 6570 and even the HD 6450. Topping out at $99, the Radeon HD 6670 offers good performance, strong HTPC features and low power consumption. NVIDIA's competition is still reasonable though as we compare how the now price-dropped GeForce GTS 450 sits into the stack.
