So I'm still not decided on my new computer, leaning toward Mac Pro because I'm video editor and the heat management + expandability is definitely a plus. But I'm on a budget so I'm looking for used ones, not 100 percent sure when one is buying 2+ years old tech. I don't care much for USB3 or Thunderbolt (I can just use FW800 when I need to move a lot of data, it's enough for me). I've come across this deal for used Mac Pro, the price is $1640, includes shipping and 30-day guarantee. The specs are these: - one processor 2,66 Quad Core - 6 GB RAM - 640GB HDD - GT120 videocard (512 megs That price is almost the same that would get me maxed out Mac Mini Quad i7 w/16GB RAM 128GB SSD+500 HDD which is something I was considering too. The first investment would be to put 128GB SSD and additional 10GB RAM (since it's 2009 model it seems pretty cheap). If the computer felt slow I can always put additional processor in it, right? (another 2,66 quad) I'm not super hardcore with my computer but my backup laptop (MB Air) isn't really up to the tasks as I do HD video editing with (sometimes) large files and I do some compositing in After Effects and video encoding. Any opinions would be appreciated.
