I currently run a 2010 Mac Pro base model and a 27" ACD. Lately I feel like this machine is overkill. In fact, I felt this way for the beginning. I originally purchased it for the idea of upgrading it. I realize now that actual parts are scarce. For example, I have one choice to upgrade the GPU to... Thats sort of silly. The room for 4 disk and other pci cards is great. But other than replacing the GPU I don't see myself adding anything else pci. As far as storage, I have never really had more than 200gb at a time. Storage is not a concern. I basically use my Mac Pro to surf the web, itunes, email, etc. and play wow and a few other games. I rarely boot in to windows and I typically never do anything demanding (photography or video). The only intensive task I do is convert flac to apple lossless. I like to always have my computer, and at times I am without it when I travel to my girlfriends house for a few days. Typically it would be 75% used on a desk and 25% on the go. I am starting to think that selling the display and the pro and going 17" is my best option. My only concern is if it will overheat when playing wow for hours on end? I enjoy the cool operation of the Mac Pro and the ability to add disks and a new GPU, but how frequently will that happen considering my usage habits and the lack of actual upgradable GPU's? Anyone with the 17" 2011 model want to give me some feedback? edit - I also want to mention I was intending on keeping my setup for as long as possible. I am concerned about high temps on the macbook pro (although I had one back in 07 that was nice, pre unibody).
