No it doesn't matter. However, Gamespy, which is the service provider for the BF:BC2 multiplayer server browser, is shutting down at the end of may. I do not believe that EA/DICE has yet announced extending support after the Gamespy shutdown, so time will tell as to whether or not the game is worth buying at all. The shutdown also affects BF1942, BF2, and BF2142. I hope that they don't drop them though.
EDIT: It does seem that EA is looking to transition them, but EA's word is as good as toilet paper so we will have to wait and see
