as a Mac user from what I have learned on this forum over the last
few years IMHO that set-up sounds just fine for C8.
Adding this stuff might also be nice
1- A killer audio/MIDI interface RME/Focusrite etc).
2-Double the ram to 16g.
3-Double the HD space to 1 tb.
4-If you can afford it, swap out the 7,200 spindle drive for an ssd.
5-Check the C8 ‘specs’ page for recommended hardware.
6-Keep tabs on the upcoming ‘Windows 10’ OS, in case you want to later upgrade yer ax.
