I will try to be short. The intention of this thread is pretty clear.
Let's discuss computer DAW's experiences and thoughts about the best configurations for audio processing and music production.
In my case after owning, troubleshooting and testing two options, the socket 1155 and 1151, iGPU and dedicated GPU, PCIe audio interface and Firewire, different speeds of RAM, HDD and SSD storage and different MOBO, I can surely say that for editing audio, is not first priority the speed or the power, but the coding (OS + Software + Plugins, etc) and configuration/customization.
Of course if you got many cores, SSD storage and a good quality RAM, you will improve considerably the performance of the system, but I mean (at least in my experience) that you can get the same or better performance in a modest but well installed system, than in one with the best technology available, but in a bad or not optimum enviroment/compatibility.
I will start with my example. SHARE YOUR KNOWLEDGE!
I was using since 2014 until last week, the 1155 socket with an Intel i7 3770 3.4Ghz (4 cores, 8 threads) with a premium MOBO, the Asus Maximus V Extreme (excellent one) using the iGPU Intel HD4000 and 32GB of RAM DDR3 Corsair Vengeace Pro 1600Mhz, lastly an SSD OCZ Vertex 4 for the OS (Windows 7 x64 Ultimate -original- but fully optimized with little touches in the windows registry) and a PCIe audio interface (RME RayDat). The system worked like a breeze. Really fluid, with at least 20 channels full of plugins (around 3 each channel, total 60 between Waves EQ's, Compressors and various FX's) in Ableton 9.7.5 (x64) and without a single drop out, click or pop.
Sadly, I had to update the rig due to a little freeze that started to occur each time more often. A clean install of Windows didn't solve it, so, time to update after 4 years of intense usage.
The best option seemed the new Intel i7 8700 -1151 socket- (6 cores, 12 threads), but this time paired with a more modest but solid MOBO. the Asus Prime Z370-A with only 16GB of RAM but DDR4 this time at 3000Mhz and with the gorgeous SSD NVMe M.2 Samsung 960 Evo for the OS and 3 SATA SSD's for the libraries, samples, etc. Same interface (RME PCIe) and a dedicated GPU (EVGA GTX 1050 2GB), paired with Windows 10 Pro and Ableton 10.
In theory everyone could say that the new setup would kill the first one, but it didn't happen at first (and I don't even know if does it now).
I tried everything, but the Resplendence Latency Monitorwas showing really bad numbers in this new rig with Windows 10 (tried many versions, original, LTSB, Original version deployed with MSMG Toolkit, LTSB custom, etc!!!) but I wasn't able to handle the known issues with the nvlddmkm.sys and dxgkrnl.sys drivers, also tried the performance with the iGPU UHD 630 but not big difference either.
Now, after 2 weeks trying a ton of different OS versions between Win7 and Win10, I downgraded to Windows 7, even when they recommend not to, and missing some drivers for the Z370 chipset, but with a great performance with exception of the hard page faults that are massive unlike Windows 10 that has 0 hard page faults but massive DPC and ISR routine execution times with my configuration.
I have a quite deep customization of the system, with 0 resources applied to the aesthetics and with many services and components of Windows removed or disabled. This is the only way that I've found to replicate the functionality of my previous rig, that's not neccesary to say that was much more old and less powerful than this one, although not in practice.
To end up, this is not the ideal situation, since I would prefer to use the Windows 10 OS for this hardware, with much better looking but specially with better administration of cores and memory, but seems to be that there is still much work to do in the coding arena, because Windows 10 works great but at least not with this configuration that is pretty popular.
CONCLUSION: The hardware is equally important as the OS that you plan to use until find the correct configuration. In my experience 32GB of RAM it's simply too much. I use Kontakt, Trillian, Omnisphere and all this kind of heavy libraries and I hardly occupy more than 12GB of physical memory, so it's better to have a good quality and fast memory than more quantity. I have a lot more thoughts, but I dont't want to make this post larger than it actually is.
DETAIL:
SETUP 1:
CPU: Intel i7 3770 (3.4Ghz)
iGPU: Intel HD4000
MOBO: ASUS Maximus V Extreme
RAM: Corsair Vengeance Pro 32GB (4x8) 1600Mhz
Audio Interface: RME HDSPe RayDat (PCIe)
Storage: SSD OCZ Vertex 4 (256GB)
PSU: Corsair CX650
EXCELLENT PERFORMANCE WITH WINDOWS 7 ULTIMATE + ABLETON 9.7.5
SETUP 2:
CPU: Intel i7 8700 (3.2Ghz - 4.3Ghz in Turbo)
GPU: EVGA GTX 1050 2GB
MOBO: ASUS Prime Z370-A
RAM: Corsair Vengeance LPX 16GB (2x8) 3000Mhz
Audio Interface: RME HDSPe RayDat (PCIe)
Storage: SSD Samsung 960 Evo (250GB) + SSD Crucial MX300 750GB (x2) + WD Green 250GB (x2) + HDD Seagate Barracuda 2TB 7200RPM
PSU: Corsair CX650
EVEN BETTER PERFORMANCE WITH WINDOWS 7 ULTIMATE (but with some errors) + ABLETON 10 now I can add much more plugins, and of course the system is more powerful but after a couple of headaches and missing some functionality due to the ended development of drivers for Windows 7 >:-( on the Z370 chipset that is intended to be used with Windows 10 or later.
Again, SHARE YOUR KNOWLEDGE and your experiences with different combinations of Hardware + Software, then maybe we can find the best combinations for audio and future updates.
Best.
