Hey. I just ordered a new 2GB ram stick for my MacBook got it for 2.99 off amazon so I only bought one not even realizing the MacBook has 2x1GB sticks in it. Is it going to be an issue runnin 1 GB AND 1 2 GB for a total of 3 GB in performance. I'm mostly doing this to run world of Warcraft better. It has the 9400m video card in it. Whenever I run wow I'm at almost a full 2GB of ram being used. Will I see a performance increase with the extra 1GB being free or will the unmatched GB type hinder the performance of wow? I read different views on this that it will only be a minescule performance decrease that I won't even notice, others say its a big deal. What are any of you smart hardware guys thinking about this for performance in wow.
