I am about 99% sure I will be getting a PS3 in soon, but I cannot decide between which model. I don't really care about backwards capability of the 80gb, and I do prefer that the 40gb is quieter. One thing I have noticed is that many of the PS3 games take up huge amounts of space on the hard drive. I would not be downloading videos or saving songs and pictures to my hard drive, but I would be saving games and downloading them from PSN as well. If this is all I am using my hard drive for, is 40gb enough?
