So... finally I took the plunge and got new Asus with TB support. Intel with 4 cores, 16Gb and 512Gb. I'm not collecting sample library so my needs for space are more than met with 512Gb.
Just fine tuning the setup as I type. Already got Cubase and my ADDA working quite properly. Next thing is the test recording down full load of tracks and see where we are with the setup.
It's a joy to mix after outdated macbook. I can have much more plugins and stuff running before touching "render in place" button.
Thanks for the pep talk! 😀
ps. I would love have Linux as OS in my DAW, but the damn thing is no good for audio (go figure).
