So lets say we have a mac mini with 2 thunderbolt displays to run "os x" on the first and "windows through parallels" on the other.
If I understand correctly with os x mavericks we shouldn't have any problems running windows in fullscreen.
So how would a mac mini perform with this config? Considering I play starcraft on windows and do small transcoding with handbrake on os x while watching a movie.
-Should I get a macpro for this or the hightest end mac mini would do it?
-Is parallels that good?
Coding in handbrake while watching a movie while running a second OS in Parallels while playing a game on it... You forgot to add juggling and baking a cake...
First of all you are clearly multi-skilled
You can do what you want with a 2.6Ghz Mac mini, and also with the 2.3 I take it, although I do not have one of those. I do that all the time, although not so much the game side of it. I am usually running business applications in Windows in Parallels on the second screen. I have also run the same on a 2.0Ghz sandy quad no problem.
You will have to accept that the CPU will be running fairly hard so the fan will run. It is not an issue at all but it will definitely be running (mainly because of handbrake). At idle the CPU doesn't break 10% and the fan it minimal but with Handbrake the CPU hits 100% and the fan max's out. I have been running at that speed for years on a number of minis with no problems. It just some people freak when they hear the fan. It is the sound of a work horse to my ears. Kind of like a V8 being given a push
You will also definitely need 16GB ram. I use Corsair Vengeance.
I do recall once trying to see what would happen on the 2012 when I ran two virtual machines (Win 8 and Linux Mint), Handbrake (MKV HD AT3 encode), Aunsoft Media (same as Handbrake) and two monitors with the virtuals on the second monitor. The mini just chugged along for hours. It took a little longer to process the transcoding due to the sharing of the CPU but other wise it was fine.
As for a comparison with the new Mac Pro... Clearly the Mac Pro is (or will be) streets ahead in its capability, but will also be a lot more cost as well. I have a 2.6Ghz quad mini and it can handle what you want to do day in day out. Not problem.
I am not a gamer though so I cannot confirm that side of it.
P.S. Parallels is very good.
