Hi everyone: I'm new to the forums and am having a little buyer's remorse over the refurbished '08 8-core Mac Pro I ordered last Thursday. I wanted to poll people before it arrives, since Apple's return policy is heavily dependent on whether or not the product's box is opened or not. I'm a graphic designer mostly print and web who also works part-time in Windows for one of his clients. I wanted a system I could load Windows on as a virtual machine (via vmware fusion). I'm also looking to get into 3-D and possibly some animation work in the future, but because of the age of my system, has not been able to seriously play around with some of the tools out there (Maya, etc). This was another reason why I wanted to get an 8-core, and not a 4-core system, in case I really get into it in the future, this system will serve me well over the next 4, 5, 6 years. Currently, I'm running a dual 1.25 G4 mirror door Power Mac with 2GB RAM. While I've been very satisfied over the last 6 years with this purchase, more and more, I'm feeling the pain of the older processor with lack of speed and spinning beach balls when applying filters, 3-D effects in my CS3 suite. I also know I can't go to any OS beyond Tiger with this system, since Leopard+ requires an Intel chip and lets be honest, its been 6 years since I bought this refurb dual G4--its time! So, I've been watching for refurbished Mac Pros over the past few months, and finally the timing worked out where I was able to buy an '08 8-core Mac Pro tower with 2GB RAM for $2400 shipped free...here's the basic specs: Two 2.8GHz Quad-Core Intel Xeon processors 2GB (2 x 1GB) of 800MHz DDR2 ECC fully buffered DIMM 320GB Serial ATA 3Gb/s 7200-rpm hard drive 16x SuperDrive (DVD±R DL/DVD±RW/CD-RW) ATI Radeon HD 2600 XT 256MB (two dual-link DVI ports) I'll probably add another 8GB of RAM, which should hold me off for quite a while. I'm also on the lookout for a suitable >20" LCD display that is a good/cheaper alternative to the Apple Cinema displays. Since I ordered, I've had this nagging feeling that I maybe should have gone with a 4-core "Nehalem" processor that is in the '09 Mac Pros. Its $100 more, but with half as many virtual processors, among other specs...I've read that the previous processors in the system I just bought have a memory "bottleneck" that was solved with the new "Nehalem" processors. Has anyone seen if this is really a significant difference between the two? Is my concern baseless? While I know no matter which one I ultimately go with, they'll feel light years beyond what I'm currently running. I'm also reading that much of the software I use doesn't take advantage of the 8-core architecture, which makes me wonder if I really need it. I really can't justify spending more than $3000 on a desktop system, but if the newest systems are significantly better than the '08 predecessors, I might consider plunking down the extra $600+ beyond what I currently spent on the refurb for a new 8-core "Nehalem". Or even $100 more than the refurb for the 4-core "Nehalem". Any insights to either debunk or justify my current buyer's remorse would be greatly appreciated! The remorse is really dampening what should be an exciting purchase for me ;-). Thanks in advance!
