NVIDIA this morning released its cheapest ever graphics chipset based on its current Fermi core. The GeForce GTS 450 scales back to 192 effects cores and a 128-bit memory bus but is expected to be on par or faster than its arch-rival, AMD's Radeon HD 5750. It's pitched as an alternative to integrated graphics as a partial GF106 core is both cheaper and much more energy efficient than a full GF106 core or earlier designs.
