Simple RAM Question

[Pickoff]

I am getting a MBP in mid-june, and have been doing my homework. I do a lot of video editing and Photoshoping so I think it would be smart for me to get the 2GB of RAM option if it wasn't about $220 over what it should be, so I will be ordering it from some third party site.

Heres my question: I have never needed to add or replace RAM before, so this may seem stupid. When adding more RAM, are you simply adding it into the slot, or removing the current RAM and replacing it? In other words, the 2GB that comes with it are removed and replaced by the 2x2GB? Also, is there any real difference between the pre-installed version and third party RAM?

Thanks.

The RAM thats in your notebook is replaced by the new ones you order. Save the old sticks in case you have trouble with the new ones though.

If you order the right replacement RAM, it shouldn't be any different aside from the larger capacity.

Your MBP will come with 2 1gb sticks, each occupying one of the two slots. Buy your own 2gb sticks (2 of them), and you can replace the 1gb sticks with your 2gb sticks for 4gb in total. The only difference between your memory and Apple's memory is that yours will cost hundreds of dollars less. I'd get mine from Newegg.
