I need some help with a couple of things. I just bought a new mac pro with 8-core (2 - 2.8 GHz Quad Cores). It has 2 GB of memory. I heard I need to upgrade memory in matched pairs. Can I do anything with the 2 GB that the computer comes with? I'd like to get to 6 or 8 GB total memory.... what would be the best way to do this? OWC shows a variety of options (1 GB modules, 2 GB modules, etc.) but I don't know what to buy to be able to make use of the 2 GB that will be in my new MacPro. Do the Mac Pros come with one 2 GB module in one bay or two 1 GB modules in two bays? Suggestions on what to buy to work with what is in the computer? Are the Mac Pros noisy (fan wise)? I'm hoping not. I read that the drive bays can take up to 750 GB hard drives... so, will 1 GB drives not be fully accessible in the Mac Pro? (I have a 1 GB Seagate Barracuda I was planning to install in the Mac Pro). The computer comes with a ATI Radeon HD 2600 XT.... is this a decent graphics card for Photoshop use or will I be wanting to upgrade? I just ordered the computer from Mac Connection and it will arrive tomorrow... I'm so excited.... I've been wanting this for so long! Thanks for your advice.
