just a tip, but if you are fine with a 4790k then you will probably be fine with a 4770k as well. It's not complicated at all to put the multiplier on the 4770k to 43x and the CPU voltage to 1.3V, if you have a decent cooler. I've done so on mine, so the CPU runs fixed at 4.3GHz, and on heavy benchmarks such as Prime95 (which is basically stressing the CPU to the absolutely max) i get no throttling and the temp is around 65-67 degrees Celsius. This is on a EVO212 air cooler (http://www.coolermaster.com/cooling/cpu ... r-212-evo/).

All 64 Channels loaded fine and while I only use 24 these days, the extra headroom from a 4790k allows heavier submixing in Host Application.
I usually use 14GBs of RAM 4 Kontakt Instrument Banks, PLAY Hollywood Strings, PianoTeq 5, Zebra2HZ, Keyscape and Omnisphere.
An additional 36 channels of audio clips are submixed down to 2 x ASIO too.

Omni and Zebra are core locked to CPU 2 and 3 and use 60% and 75% respectively.
On the 7700k it's lower by 10%.
So the extra 200MHz helps.
At 5GHz there was maybe an additional 5%, hardly worth the risk of excessive heat.

I'm more into compatability with chipsets than brute force these days.
As long as Scope moves ahead without being trampled by planned obsolescence from Int€£ and Micro$oft I'm good to go.

Great to see that all 64 Asio channels could be used with both those beasts (I'd probably never use anywhere near that many channels with my small modest projects, but it's awesome that capability is there for others who may need it. In conjunction with super large DAW sub-mixes and Wave drivers that 64 Asio channels should handle the most demanding projects generally.)'

As for that 10% performance increase you stated the 7700k has over the 4790k, that's around the typical small bump each new generation gets usually. It's usually around 10 or 15% with rare surprises. That 10% advantage the 7700k has may not all be due to the .2ghz speed increase but something else in the newer architecture. You would need .4ghz for 10% speed increase on a 4GHZ processor thus .2ghz is only accounting for 5% increase. But there may be something else I'm not understanding so I definitely could be wrong.

That's very interesting that when you did a huge overclock to 5GHZ there was only a 5% performance increase; overclocking in this situation seems like a total waste, with all risk and little reward.

This is invaluable stuff, you've been a lifesaver :o ..

ASRock always comes out with server versions and workstation versions later in their ASRock Rack section.
I found these to be long life, no frills audio friendly beasts.

Cant wait for the Z270m WS.
If it's anything like the Z97m WS it's a must have.

Im actually quite happy with headroom on the Z97/i7 4790k CPUs.
Just wanted to make sure Scope could move ahead using Windows 10 and Z270s.

A Z270/i7 7700k is a great ASIO rig though, there's a Z270 Pro 4 from ASRock with 32bit PCI Slots too....
