Greetings,
My good old NVidia GTX 260 core 216 graphics card has 55nm GT200 rev B1 chip, but Speccy (i tested this with version 1.06 and 1.07) reads revision number as A2, therefore it "detects" 65nm build process and 192 cuda cores. See screenshots of Speccy and GPU-Z:
I read through the forum and I didn't find any similar cases yet, so I'm sending some debug logs and my system specs to help developers kill this bug.
