Hi -- first post ever here -- at any rate, Saturday I bought a new mac pro (Two 2.8GHz Quad-Core Intel Xeon - 8 core). I basically bought this because my old G4 finally kicked the bucket Friday (and I had been wanting to upgrade for a while too) and I needed to be back up and working in some capacity by Monday and this was what the apple store had in stock. At any rate... I was looking for suggestions as to what I should upgrade the memory to. I didn't buy any from apple as I know I can get it cheaper elsewhere -- probably will order from OWC - just don't know what I should buy. Right now, I just have what it came with. I do graphic design (with a little bit of packaging design and a minimal amount of web). The main programs I use are InDesign, Illustrator, Photoshop, Bridge... (I am upgrading to CS3 as I type this -- should be in the mail). Also, I am starting to run out of space on my old external hard drive. Thinking of buying a Western Digital 750 GB -- does anyone know what the difference between their Home, Premium, and Studio lines are? Can't seem to find anything... Suggestions for either? Thanks in advance!
