Just because it's listed above the 6830 based on one single bechmark while the 6830 doesn't have a single benchmark to it's credit doesn't really mean anything... You have to take notebook chec with a grain of salt too, if you look at any of the more popular GPU's and expand their avg benchmark scores, you get a wide variety of systems used and their benchmarks will very greatly. Either way, I would've been happy with either GPU.
