If you’re wondering about components etc there’s a very long thread on Gearslutz.com that has a ton of info. I recommend starting from the last post and moving backwards towards the beginning (the thread is that long).
Also check scanproaudio.info and search for “dawbench”. It’s a test they use to compare different CPUs. The two tests are the “DSP” test which is more focused on plugins and then the “VSTi” or “Polyphony” test which runs a virtual instruments at different buffer settings to see what polyphony numbers we can get.
Just figured I’d make this more apparent since so many ask questions here but there aren’t a ton of responses…
