Hi Mac Forum friends, I need RAM advice. I have a 3.06 iMac (CORE 2) with 4GB of ram and I am noticing my computer is getting sluggish with all my applications (Photoshop) and Parallels 6.0 running. It is obvious I need to upgrade and I am not sure as to what I should go with as far as noticing a performance increase. Of course I understand 8GB of RAM is better than 6 but will the extra 2GB make that much of a difference? I need help!!! Also, is OWC or Crucial RAM just as good as say Kingston? Sorry for the dumb questions!!! I need help ASAP Thanks JENNY!
