I know pretty much what specs I want on my new 2008 mac pro, but I am uncertain as to rather or not to upgrade the processor to 3.0 Ghz. Basically, the Mac Pro will be used for Dreamweaver, some minor video editing and LOTS of 3D rendering such as Poser, Vue 6, ZBrush, etc. I was leaning to the 3.0 CPU, but I think maybe the stock 2.8 Ghz will be fine. Some of those software makers say their software will work OK with 10.5 OS BUT only take advantage of 4GB of memory and anything beyond that it won't see. Also, while they are updated and work fine with current Macs and Leopard, they may not take FULL advantage of the multi core CPUs until later. That is why I was leaning to the 2.8 and saving $800 but if anyone uses 3D software a lot or sees why I need to invest in a faster CPU than the stock 2.8 please let me know. What my thinking was maybe Summer 2009 if I REALLY need to upgrade with a new Mac Pro and just getting the 2.8 for now. Any thoughts on this for processor speed or any other tips for buying the Mac Pro now? Thanks.
