sorry i forgot one question, how do i know what the low profile one is, and is there any electronics store where you could get this besides buying it online (2 questions actually)
Most electronics stores tend to overprice their cards, and tend not to carry low profile versions if there is a normal sized version of the card available. You are probably best off ordering online. For the online retailers, under the specifications of the card there should be a row that says Low Profile, and it will either say yes or no. Obviously go for the version that says Low Profile: Yes. If you buy locally, it should say so on the packaging whether it's low profile or not.
