I'm on the fence about building a PC or buying a mac pro. My overall budget is around 1200$, but that has to include a monitor. I can do hardware upgrades, not afraid to upgrade a CPU. My question is this: Is an earlier generation Mac Pro still a viable workstation? Primary Uses: Photoshop CS5/6 Occasional gaming. (Most of my games are not intensive, but I'd like to play GTAIV and perhaps try my hand at Crysis) The rest of the time, it will be used for internet, and perhaps some VM's and other nerdy stuff. Macofalltrades has some decently priced machines, with a 1,1 starting at 650$. How long would this machine last me? They also have 2008 machines with EFI64, but they're at the very top of my budget, and I'm not too flexible on that. I could go with a cheaper machine and flash a video card for an upgrade, I'm thinking a 6870. All the threads I've found so far about it are old and stale. Thoughts? My main concern about buying an old MP is RAM. The FB-DIMMS are both expensive and relatively slow, compared to DDR3. However, RAM is still pretty quick compared to everything else, so will I see a noticeable bottleneck from the RAM? I'll be working in some RAM heavy environments, such as bulk files in Photoshop and virtual machines. And finally, I'd like to take this machine to college with me, at least for the first year. So, the machine would need to last another three years, however I may be able to upgrade before then, we'll see how scholarships play out. TL;DR 1: Is a Mac Pro 1,1 or 2,1 still viable for Photoshop and moderate gaming? 2: Would the RAM be a significant bottleneck? 3: Do you guys think Mountain Lion is really going to drop support for older MP's, or will Apple add support at the last minute? 4: How long could I reasonably stretch the machine, time wise? 5: What about upgrades? Flashing video cards and upgrading the CPU?
