I have two boards with an I7 running with air-cooling 24/7 and the main system with the water also
The difference is about 10 degrees in the same room without cooling the air.
My oppinion was, to spend more money on the mainsytem, to get more lifetime of the system.
The main performance with overclocking and not, was no big difference, and 5ms of delay in the
fader movements, was ok for me, so the speed of the system was fine.
The mix of RME totalmix is about 0.5ms and the two Computer, with I7, have 1.7ms delay.
They work with the Sampler and Drumcomputer.
So its possible to get the SD3 Drums running with a V-Drum, with about 2ms of latency,
or NI Komplete with a sampler or a synthesizer
Midi was too slow, so I have to use a keyboard or a drum kit with the USB- Ports.
Back to the start, the CPU is only a small part of the whole system, and it is the balance between
all the stuff you have and you need.
The big difference for me, is the SSD, Raid, and M2, together about 50% of the whole performance.
Also if you use 32 tracks only, and not a big outboard gear and 200 plugins, a raydat sytem with I7
can do the same, with one computer. it really depends how is your workflow.
One of the bad things in the system is the internet. Never change a running system.
I make a copy from my System, when it runs new and save.
Every month I put this sytem back, sometimes earlier. And no internet on the whole system.
If I have to use it, this is a total seperate Computer.
good bye together
