Got a MacPro a couple of months ago. It's not time to upgrade and need some help. I bought the basic version with only 2 MB. From reading here, it seems that OWC is the place to go. I will be using CS3 with Aperture and Final Cut Express to edit HD video. I will also be adding a 30" monitor. How much RAM do I realistically need? I know more is faster ... but more expensive as well. Also, how easy is it to install? And where do I go to get instructions as to how to install? I am pretty handy, but have never touched the inside of a computer. Need to do the same with the hard drive as well. Only have the base 300 GB drive. What should I consider here? Should I add to my tower? And if so, what should I consider? And the same question regarding how difficult is it and where do I find instructions to do so? Sorry for the long post. Thanks in advance for the help!
