Core i 5 is GENERALLY known to be faster especially with multitasking . However , not always the case . If the i 5 is quadcore then by all means , it is much more powerful for gaming among other things . i 5 will also have a larger cache , which is good for repetitive tasks , and it has turbo boost , both of which help with overall performance in all areas . You just have to justify the price difference , and I can ' t really offer too much help with that . <| sep |> Lights are green then start flashing green , then turn yellow and finally red . Basically once you see it flashing green you need to decide to slow down and stop or speed up and pass the light . Once the light is red it just turns to green without any warning . Besides that and driving on the opposite sides I don ' t think there are any major differences .
