This is why I want a Mac Pro. I don't need 128GB today. But in five years? Maybeand probably for less than $150 by then. My MBP in 2008 had 2GB of ram and my current rMBP has 16GB. Though I rarely hit a limit with 16GB. The limit I hit fairly often is the 512GB of SSD. I think someday RAM and SSD will be one in the same.
Tell me if and why I'm wrong: I'm thinking the Mac Pro could be my key to not doing upgrades every two years. With upgrades to 12 cores, upgradeable video card, upgrades to 128GB of ram and Thunderbolt 2.0 storage I could probably get 6-7 years out of it. 64-bit multi-core Geekbench score for the baseline late 2013 Mac Pro is 14426, while the top-end early 2009 Mac Pro beats it handily at 17795. If Apple waits until 2015 to update the Mac Pro again, the new baseline will probably be near that score around 18000. That will be around 6 years. So if you bought the 2009 Mac Pro at a base configuration (Geekbench 8075), and then upgraded to 8-core and more (17795) later when it became cheaper, you could do as well (in theory) as a baseline 2015 Mac Pro. Those of you who have upgraded older Mac Pros, please tell me if my logic is flawed. Can you go from bottom to top-end through upgrades alone over the course of several years without spending as much? Or is it better to just sell your machine every few years? I hate dealing with Craigslist, but it has worked for me in the past. It's just always stressfulespecially for such a pricey item. I don't need the top-end Mac Pro, but I do a lot of work that could benefit from a higher-end machine with a large, pixel-dense display, such as editing lots of photos, Photoshop work, web design, lots of multitasking, testing websites in IE in a virtual machine, and some video editing (720p and 1080p). I'm going to be purchasing the successor to the 5D MkIII when it comes out, so those files will probably be huge. Especially if they increase the dynamic range and megapixel count. So a low-end Mac Pro with 4K seems like a good idea. But will it last for a long time through upgrades?
