I would suggest the Asus Z97 Pro instead, so that you could use the M.2 SSD and bypass a few extra seconds start time. I mean since it seems so snappy to you and all. I use a SATA III bound SSD myself and by comparison the M.2 method is just better all the way around (except cost of course).
That said I do not see anything wrong with sticking to nothing but HDDs.
Aside from that nothing really pops out at me. Nice sound card choice.
Was that directed at Tumor, Bellator, or Me?
I already have my system built.
I only needed one PCIe 3.0 X16 slot, I can't and don't want to overclock, and I found that 2 Samsung Evo 850 500GB Sata SSDs in raid 0 where a better option from a price vs performance standpoint over m.2 That's why I went with the MB I did, and it only cost me $70 bucks.
M.2 Sata drives are still limited to the Sata bus limitations. PCIE M.2 drives are the ones that really get the performance boost. I think the Asus z97pro does infact support m.2 in both both PCIE and SATA modes. However ....
I have sequential read/write of 1050/1022 MB/s 4k Random read/write 384.7/350.0 MB/s (Remember I'm running 2 drives in raid 0 so speeds are double)So I'm getting a 1tb partition with PCIE m.2 speeds for about 1/4 the cost.
The sound card was to replace my X-Fi pci fatal1ty platinum champion edition. The X-FI sucks (3 audio modes is a bad joke) compared to my Audigy 2 ZS Platinum and I wanted a simple sound card that's better than on-board with DD live, DTS, SPDIF (I have the Logitech Z-5500 speakers) and I want to use my cases HD audio ports. My set up allows me to run 3 sets of headsets 2 of which are RF wireless.
