My 21 month old Mac Pro is getting really crazy these days. Though it has 3GB of installed memory I have been adding so many startup items, so many icons in the dock, and running applications such as Photoshop, EyeTV and Safari at once that I am getting slowdowns, choppy TV playback and spinning beachballs galore. Obviously I am taxing my Mac Pro's resources. Crucial has a really cool website that scans any Mac, tells you your exact configuration, and then suggests memory upgrades. For about $119 I can add two more 1GBx2 modules and bring my unit up to 5GB total. For $181 I can buy 4GB of memory bringing it up to 7GB total. A few questions.... 1. Is Crucial good memory? 2. Is it easy to add memory to the Mac Pro? The Crucial site shows pictures of the memory bay and its empty slots. I would imagine all I need to do is open up the back, find the memory bay, and insert the memory chips. That simple? 3. Will the added 2-4GB of memory (bringing me to 5-7GB) cure the slowdown and spinning beachball problems I am experiencing due to the amount of startup programs? Will this be the cure? 4. Will the added memory increase bootup and file loading times as well? I don't mind going up to 7GB. It may sound like overkill, but it certainly sounds as if I will have unlimited head room to play with for some time. Thanks!
