Hi, everyone. I am planning to purchase a new laptop and I am trying to decide between i5-430m vs i5-520m processor. I looked at the benchmark results and I am not quite certain what these results mean. Overall it seems as if the differences are not too big (for example, >50%). I am primarily using the computer for internet, office application and video encoding. Is it worth $80 to upgrade to i5-520m? Would I see a significant difference in the time needed to convert a video format or rip a dvd?
