Hello, I am loving my new Mac Pro. I am kind of pissed that I didn’t switch to a Mac sooner, but that is water under the bridge. I literally cringe on the rare occasions I have to boot into XP. The Mac Pro is great, but there are a couple areas that are a little lacking. Thankfully, they are very easily upgradable: the ram and hard drive. I bought my Mac Pro with the stock 2GB of ram and a 500GB Hard Drive. I only have the money to upgrade one of the two right now (I am a poor college kid), and I am not sure which to upgrade. The 500GB hard drive is atrociously slow. It usually scores in the 40s in Xbench (My 7 year old Western Digital scores about the same), and it significantly slows the loading of applications. The 2GB of ram is decent; I don’t max it out often, but sometimes I do with very heavy multitasking. I don’t use many design or pro-apps, but I do run several reasonably memory hungry programs (100-250 megs of ram per program). My question is: would it be better to get another 2GB of ram or a fast hard drive like the new 640GB Western Digital? Which would see the biggest performance increase? I had read that getting 4 pairs of ram dimms can increase general speed in the Mac Pro? Is there any truth to that? Thanks!
