nVidia already working on 90nm circuits

nVidia has relatively recently launched its G70-series which uses the 110nm process. ATi is currently working on the R520 abd its sibblings with a 90nm process. According to nVidia 90nm is not something it is unexperienced with as it is namely producing two 90nm circuits already. It is uncertain what circuits we are talking about but most likely a low end series of G70. Just as the high-end of the NV40-series was made with 130nm while the low end was 110nm.
