Hi there. I actually work for a CLEVO brand, and i even work with PCSpecialist (as a partner) :P
Can you tell me whats the model of that laptop? Since there is firewire i would guess it is a P series, P150SMA or P170SMA.
First thing i notice is the graphic card, let me just tell that you are getting a switchable graphics system, it switches from Intel integrated VGA to the dedicated VGA. For Audio the current gen NVIDIA cards are just BAD, 600ms DPC... so when doing Audio just disable the NVIDIA card and use the Intel Integrated.
I currently only use M290X on CLEVO laptops for Audio, NO DPC above 100ms.
Even if you disable stuff like NVIDIA powermizer it will still be a lame card (im really mad with them for some time now).
As for the firewire let me give you a good news, it's a really good controller, its texas instruments!
I can also supply you my modded BIOS / EC, it will allow you to tweak the BIOS and disable stuff like turbo boost, C states, internal audio, internal lan, etc... its useful if you want to tweak it to the max, or in this case to the min DPC.
By doing minor windows tweaks and disabling devices you dont need, that laptop can get you REALLY low DPC.
I would also use ThrottleSTOP app, with it so you can lock the CPU at a fixed speed! ;)
About performance... its a monster!
Anything you need let me know.
