Macbook Ram Speed Question (1033 or 1333 MHZ) I have two 4GB modules of ram for a Macbook Pro (1033MHZ).
I have a new Macbook pro that came with two 2GB modules (1333MHZ)

Would it be best if I left the 4GB faster ram in? Or would it really be noticeable if I swapped it for the 8GB of slower ram?
Depends on what you plan on doing with the machine but 9.99 times out of 10 you're better off going with more ram (8gb in this case), especially for RAM-intensive applications such as databases, virtual machines, music/video/audio/photo editing.
