Looking for some advice. I'm a graphic artist and photo retoucher who primarily uses Photoshop, InDesign and Illustrator. Sometimes I need to work on some very large PSD files, but I do only a little iMovie work, and no gaming. It's well past time to upgrade my Dual 1.25 GHz G4 with 1.75 GB Ram on which I've made my living for almost 4 years. The new Mac Pros look great to me, but I wonder if the one 2.8GHz Quad-Core Intel Xeon (quad-core) for $500 less than the 2 2.8GHz Quad-Core Intel Xeon (quad-core) might not be a better machine for most of the work I do? From what I've been able to gather, CS3 apps aren't multi-processor savvy at this point, and there wouldn't be much of a speed boost for these apps at this time between quad or octo. But, perhaps someone could tell me if there will be much of a speed difference in the future when Adobe updates the CS3 apps to take advantage of 4 or 8 cores? Would $500 would be worth it in the future if I went for the 8-cores now? I think I'd rather go with the single quad core and then spend that $500 on third party RAM and hard drives? Advice appreciated.
