Music production build ideas?

Hey everyone 🙂 I’m looking at building a new PC for music production. Nothing crazy, just enough to make sure things don't lag. Gaming isn't my main focus since I mostly play League of Legends, though I might pick up something newer occasionally just to kill some time. 😁 Anyway, I'd love to get your take on which direction I should go...

- Motherboard: ASUS Z97A or ASUS H97 Pro
- CPU: i5 4690K or Intel Xeon E3-1231 v3 - RAM
- RAM: G.SKILL Ripjaws X series, F3-12800CL9D-8GBXL
- HDD: Western Digital Blue, WD10EZEX
- SSD: Samsung 850 EVO 250GB
- Cooler: Cooler Master Hyper 212 EVO
- GPU: - ASUS Radeon R7 250 x 2 or
- EVGA GeForce GTX 750 ti FTW
- Optical Drive: doesn't matter
- Case: Fractal Define R5, NZXT Source 340, or Fractal Design Define
- PSU: Not sure if I should stick with the Corsair CX Series 600W or something else?

Just one Intel Xeon E3-1231 v3 (8M Cache, 3.40 GHz).
Just a single 16GB kit of Kingston DDR3 1600MHz, CL11 (two 8GB sticks).
Just one SanDisk Ultra II 240GB SSD here. It’s the standard 2.5” 7mm SATA 6 Gbit/s model, with read/write speeds around 550/500 MB/s and random IOPS at 91K/83K. Retail version.
One Kolink Deathclaw Gaming case, Black, featuring USB 3.0 and three 120mm fans.
Just one 1TB Toshiba P300 hard drive, 64MB cache, spinning at 7200rpm.
Just one Palit GeForce GTX 750 Ti 2GB DDR5 StormX OC.
I guess there's one LC-CC-95 CPU cooler here—it's compatible with Intel or AMD and uses a standard 90mm 4-pin connector. Maybe that's all anyone really needs to know.
I guess I have one ASRock Intel 1150 Socket B85 Anniversary motherboard available.
Maybe an Intel 1150 Socket B85 Anniversary motherboard paired with a Super Flower Golden Green 450W (80+ Gold)? I guess that could work.

Total: $2315 Futura-IT

It’s absolutely vital that you invest in a high-quality motherboard and power supply if you want to minimize those pesky ground loop issues while you're recording.

Yeah, I probably should've just gone with the ASRock H97 Pro4 from the start. Anyway, thanks. 🙂
