I'm looking for some advice from the DAW builders. I'm getting ready to build a new DAW PC for my Presonus 32.4.2AI that I use in my home studio. The current PC is an almost 10-year old Dell XPS 420 that is yearning for retirement as a surfing/email machine. Budget for the build is around $2600.

I've looked at the custom build sites and decided I can build my own for less dosh and get better specs. I have decided to model my build based on the Sweetwater CS450. Here are the notable changes I am making:

ASUS Z170-A LGA 1151 Intel Motherboard (same as Sweetwater CS450)
Intel Core iT-6700K 8M Skylake Quad-Core 4.0 GHz Processor (they use the 3.4GHz version)
Samsung 960 PRO M.2 512Gb NVMe PCI-Express 3.0x4 Internal SSD (OS and programs - they use the non-pro version)
Seagate BarraCuda Pro ST2000DM009 2Tb 7200 RPM 128Mb Cache 3.5" drives (2 in a RAID 0 config)

My question is centered around the memory for this build. I am planning to go with 64Gb. The motherboard will support DDR4 3466 MHz (PC4 27700), but is that really necessary for a DAW build? The cost for memory with that spec is around $700. Sweetwater is using DDR4 at 2133 MHz (PC4 17000). I can get PC4 17000 memory from Crucial, Kingston or Corsair for around $400. Is it really worth spending the extra $300?
