Fleetz....
As Noel states most DAW software has it's place.
It a matter of finding one that has an interface and workflow that is appealing to your way of thinking/learning.
Many companies offer demo programs should you decide to try something other than Cubase.
(I've been with Cakewalk since 1993 and use Sonar X3.)
Personally, I don't think (2) separate PC's is necessary.
Just one that has sufficient beef to accommodate the demands of audio recording/processing.
Do you already have monitors?
You'll likely get a plethora of suggestions here.
Good luck....happy spending.

Back to it....
