Not that I don't understand the urge, but these requirements are MASSIVELY overkill for a DAW machine. It sounds like you're using crappy old school DAWs (ProTools excluded-ish). Good DAWs use all the threads available and aren't super resource heavy like that.
I run huge project files with Melodyne and tons of virtual instruments and I've had no issue whatsoever on 16GB of RAM on my 5820k. I'm talking up to 8 guitar tracks all with BIAS FX impulse response based virtual instrument emulation then with pedal chains of 4-5 pedals on each channel, just in the instrument. Then 4-8 plugins per channel for standard stuff, EQ, compression etc.
I'm using Reaper though, which is efficient, and highly multithreaded. It runs really well, all the time. Forget Logic or pretty much anything but Ableton Live, ProTools or Reaper. Everything else is legacy in my mind. Single thread in a DAW is due to nothing other than low quality programming and old out of date code. DAW is the perfect use case for multithreading.
Don't think you are reading into everything I'm really saying.
First off, I haven't touched Pro Tools since October. I got Studio One (Which I ADORE), and Using Reasons.
So for your information, I've downloaded some new plugs, that are sample based, especially when it comes to things like Piano Samples and strings. And I want to do that at a lower buffer. I ran two instance of my new String plug in, and my CPU usage went from 30% to 100% and was in popping hell. I can raise the buffer past the 256 setting I have, but then it becomes not playable in realtime. Note that is JUST Reason, and not including when I need to run those Apps simultaneously. Heck, some of the new VI's in Reason takes a lot more horsepower than when I first started this journey. My Piano sounds takes 5-10 seconds to load because it is layered in so many samples. These aren't "Basic" sounds. I just receive the new Processor and it seems to help a little, but still not perfect yet, but it shall do for now.
And 8 Guitar tracks? That is cute. I already got sessions imported over where I have 50-200 tracks. Some I'm testing. One I've imported from Reason that is 20 tracks alone, and that is right now without vocalist. And while most tracks I have three plugs, some can be up to 12, with routing and sidechains. That takes up processing. And I've been buying plugins and those matters too. Not all plugs made the same.
And that is not including the CAD work that I'm now doing for a company I'm trying to start. That has its own requirements.
Times has changed, and I've was already planning to get a very powerful rig. I'm not buying for "Today's" need like you are insisting.This is a rig I want to last for another 10 years. I need a multitasking BEAST! I need RAID-On-CPU tech for M.2 Drives. I need a handful of SATA drives now (Currently got six).
I've just built a FreeNAS server for redundancy, and Looking at my options for a offsite backup because this is something I'm planning to make money with. This isn't just for Sport for me. And seeing other rigs that people is building on here, mine isn't soo far-fetched. My Current Rig I've invested over $3,500 into it,so this new build won't be far off. I need this to also help save time from loading samples and doing renders, since time is money.
That is why I need this "Overkill" of a machine.
