I've been wanting to buy a Mac desktop and have some questions about the Mac Pro. I'm not entirely sure if it's overkill for my needs but there's no indication if a midrange tower is coming soon. I don't want an imac or laptop and the mini might be underpowered and isn't as upgradable. I do some DV editing of family videos only. But I do alot of photography and work in RAW alot. I understand the Mac Pro will really shine with PS CS3. Configuring the Mac Pro - would you recommend going with a 2ghz and 2gb of RAM or 2.66ghz and 1gb of RAM? Both configurations end up costing about the same (with all other configs being the same). I guess the 2.66ghz is better because it's cheaper to upgrade RAM down the line rather than a processor. So is that the best route to go, or is there such an insignificant difference between a 2ghz and 2.66ghz processor that it doesn't justify the price? I can always add even more RAM to the 2ghz with 2gb RAM upping it to maybe 3 or 4gb later. But is what is essentially a workstation really overkill for my needs? Can I take advantage of two dual core processors? I'm going to keep my PC separate for gaming purposes to save on upgrading the graphics card too. Thanks for any help.
