Here is a thread that has probably been posted a thousand times, but this one is slightly different. I want you to explain why you have chosen this hardware. What do you do? What is your use for it?
I currently have two computers, a 2009 17" MBP with the usual specs (2.8 GHz and 8 GB of RAM) and a Hackintosh (i7 and 32 GB of RAM and GTX670 GPU and Samsung 840 SSD).
Both perform well, the MBP is for using it at work, though nothing CPU intensive, and when on travel. The desktop is for home use and editing and compositing.
I notice that some people have 16GB+ RAM. Is this just for your own status or do you use it? If you use it, how? Do you find it future-proof?
8 GB or 16 GB of RAM might be enough for most of its use, but when I do After Effects work, the extra RAM is really helpful. Since RAM was also quite cheap, 200 for 32 GB, it was a no brainer.
I would have gotten a Mac Pro, but for my needs it would have been overkill, since I do not use the CPU or RAM that much on a regular basis.
I would not mind the current Mac Pro though, just for its form factor.
The Mac mini was not really an option, since I have 10 TB of storage inside the Hackintosh and while I have lived for almost a decade with external HDDs, it is kind of nice to not have to worry about external enclosures for a while.
I could however could have gotten a S-ATA or Thunderbolt enclosure, but not yet.
Currently my work, on film or commercial sets, does not require me to have that much computer power, but if I ever would have to do editing and compositing on a large scale, last year I was down a big project with lots of compositing and rendering, 270 minutes of final product, I might go down the Mac Pro route, if the money is right and such a computer would be helpful, as even the i7 can be slow when rendering that much of data.
Anyway, I always maxed the RAM on my computers, thus I probably have that just in me to do so.
