I was raised to never overclock a cpu , if one wants it to last a long life...even with heat sinks or water cooling of the best sorts...
I also believe at certain points in overclocking, some things do not time out well...if say a outside clock is synced to the system... odd things happen, you end up frozen....or locked up....if it is true or not...??... I never went there to find out.
I am glad some can overclock without issues....Yet for my reasons above, I do not do it at all.
I have a good system build with Thunderbolt 2 Asus Quad deluxe board..z87 spec below...I think the TB interface helps relieve the memory/cpu access via directly using memory without cpu intervention.....rather than cpu being the director....So it relieves more bottle necks in that, and less hickups with audio irq issues, which to my mind with Firewire 400/800 cards from TI and LSI and others seemed to plague that PCI x1 firewire solution..or pci e card solutions with noise clicking and popping..., I once used....
As for USB audio...I am trying a motu 4 pre, on one machine...had lots of issues in the first run under win 7...but it is now working ok, after a few driver upgrades , on a older 2011 socket board with a 6 core...Streams video and audio well...and internet is ok...But I rarely use this for audio mixing or such in recording...Mostly a play back, all in all system .
My new X99/2011-3 5930 (Asus ) 32gb,ssd build, and red drives,is still being tested, also with Thunderbolt add on card (Asus) added, has moved into the recording area, to tie into the other systems for video and audio production testing....Seems to be very fast, and stable with Sonar and Studio one 3, with Motu Thunderbolt 828.
Mac Pro 8 core, runs the Allen and Health x2 mixers, over Thunderbolt 2 now, and has been the 8 core champ in all...Logic and Studio one 3 and pro tiools are on that with sound forge...and has two video cards for the video end of things, when I get the software for that.
All this, and other systems for midi/softsynths/dmx lighting...are moving into place also, to be farmed, or synced to the master Mac machine...
Dmx and such lighting to be added next....So when tempo and metronome are needed ...a light can run the tempo to the session room...to help keep time...and or control stage lighting....(As a click in head phones is never loud enough for the people playing live as a hole band together)....So light timing might be a solution for me...and dmx lighting is run off of midi/metronome click
I guess if one machine is suppose to run a audio system only...4790k and good MB will do..with 16gb of memory or more and a 2gb video card...setup right, can be fruitful to work with under win 7 and up .
I think the x99 is more robust for multi tasking video and audio though, and sure as hell will do it without too much hick up or noise, or sqweeling...and might do it a bit faster if utilizing all the speed these new boards can utilize...usb 3.1, and M2 ports, and on some thunderbolt supoort....I'd say a well built system exceeds the Mac pro...at way less a price!...value?...proven reliable?....still new, and being developed win 10...is bound to be a fixer for a while more...but seems to be stable at this junction .
Mac is also being updated and some issues with....so bliss is what you choose to make be that bliss....if it is obtainable totally yet?...no not yet, but sure is around the corner, over the hill, and not too far away!
cheers.
hope this helps unconfuse via confusion methods tested so far,the right choice out of the wrong ones I made first .......wink....Thunderbolt, with firewire adapter // works better than firewire ever did for me..
And we hope CW has fixed the lost audio device issue....as I have read they did find something odd in code...so that is next fix, to solve for...and then maybe it is bliss.
