I was wondering how your 8.1 system is set-up. Specifically I'm interested in which windows updates (if any..) are installed on the testing rig? Do you let win auto-aupdate?
Horribly :-P The system I did the test on was my work PC which is more optimized for development than music lol.
The tests in question are not dependent on any system optimizations since they purely reflect the behavior of the code in SONAR. You will see those improvements on pretty much any PC.
My DAW at home has the same processor but its a different machine and motherboard. I bought it from Jim at StudioCat. He did all the setup for it so I didn't mess with it too much other than upgrading it to Windows 10.
I always let my system update. Its pretty rare that there is a mess up. I did have trouble with the big Win10 update however - it messed up one of my machines ability to resume from suspend. Didn't affect my DAW however.
The PC in your sig looks fine as well. I tend to go for the highest multicore I can afford so I got the 5960X since I do some video stuff as well. The 4970K is also a pretty smoking processor.
