i have 2 x gtx 260 65 nm one sc and one vanilla.. i believe they are both 192 shader models.. but gpuz always read the vanilla one as a 216 model, but the texture fill rate is rated as the 192 model. i dunno is it a bug or do i have a 216 model. and uses the bios 62.00.1A.00.0A. *shrug* not sure what to say about it. just want to make sure its 192 or 216.
