Firing Squad writes: "For the past six months NVIDIA's been racing to shrink their entire GPU lineup to 55-nm. With the company currently embroiled in a price war with ATI, shrinking their graphics lineup from 65-nm to 55-nm is extremely important to improving the company's bottom line. The smaller process benefits NVIDIA by reducing their manufacturing costs, while consumers also benefit thanks to reduced power consumption (and thus heat output). In theory, this also opens the door to improved overclocking chances as well, although in the case of TSMC's 55-nm process, many of the high performance features found at 65-nm are removed in order to minimize costs.
In any case, shifting GPU production from 65-nm to 55-nm is a win-win for NVIDIA and the consumer."
