Also the X79 will still be compatible with my 3970X correct?
In reverse order;
Yes, the newer board will be backwards compatible with the 3970. . . . . It's the older board that would have had to at the least, needed a bios update to work with a 4970, had you gotten that CPU.
On your storage plan;
It doesn't have to mean forgoing the space, only changing how it's configured.
The 2 Intel 6Gb ports native to the X79 are the fastest / most reliable ones, and where you should always put your primary OS RAID drives.
Since there's just 2 of them, it limits you to 2 drive RAID 0 or RAID 1 . . . . You can't build a RAID array with drives spread across multiple port controllers.
You could build a 3 or even a 4 drive raid on the Marvel 6GB ports, but it still wouldn't be faster than 2 on the X79's 6GB ports.
Technically, you could
build a RAID with more than 2 drives in the X79's ports if you used the 3Gb ports, but then you'd limit the overall speed to the lower, 3Gb port speed, so it's not really an acceptable approach.
It also doesn't make a lot of sense to have huge amounts of storage on the OS drive.
Let the OS RAID drive do its job of managing the system, and put storage on additional RAIDS on the other controllers.
A pair of premium 240/256 GB drives for the primary OS is already somewhat overkill capacity wise, but the 240/256 drives usually have a significantly better write spec than the 120/128's of the same series, so it's justified from that perspective.
In the case of the M500 Crucials, it's a bit interesting to note that the 960 and 480 while having the best write speeds, it's still only 400 MB/sec, while the 256 &128 are well behind at 250 MB/s and 130MB/s respectively.
I would not suggest the M500 series for your OS raid array. . . . Its virtue is cost effective hi capacity, not speed.
The Samsung 840 Pro series is currently one of the most popular among performance enthusiast builders.
The 256GB version has a 520MB/s write spec and 100K IOPs spec, a bit more than 25% better than the 960GB M500's.
Remember that it's all about I/O . . . . you can't read and write simultaneously on a single drive (or raid group), but you can be reading from one RAID and writing to another.
Instead of 3 of the 960GB Crucials all in one group, get 2 of the 960's for a storage raid, and 2 of the Samsung Pro 256's for the Windows OS raid.
You'd actually save significantly in initial outlay and have a more workable plan if you get a pair of 840 Pro 256's for the OS to start, hold off on the 960's and put that $$$ into a GPU you want, either a Titan, a R9-290X or maybe a 690 or a pair of 780's.
