so my father has a macbook pro sitting in his closet... turns out he doesn't need it and never opened it and it just sat there... its from mid 2010 now i discovered it, freaked out, and told him he should give it to me. i doubt we can return it and update it to a new one... even if its never been opened. so here are my questions: is the i5 3mb cache still good? and its from mid 2010 so if I install lion will it have problems cause I've heard a lot of problems with lion and computers from this time. especially if my graphics card is nvidia gt 330 which it is.
