So i recently took the plunge and picked up a stock mac pro plus the 8800gt, im still clueless about mac osx though. I plan on using my current 150gb raptor as the osx system drive/apps. Now heres my first question i plan on using the stock 320gb as both a scratch drive and windows drive...is that possible? say 100 for windows 200 for osx scratch disk...i ask because osx doesnt use the same formating as windows correct? so is this possible and how would i go about doing it? gonna throw in a 1tb f1 for all data. As far as memory i read the whole thread but i am still confused...i understand that they are best in groups of 4 or 8 matching....So could i get 6 1gb owc sticks and use the 2 1gb stock sticks that come with it or would that not be optimal...8gb is fine for me and i dont see the need for anymore at this point so filling up all my dimms is not an issue.
