8 Solid State Drives are incredibly dangerous. I understand this was a matter of kinky 3.8GB/s speeds, but 8 SSDs in RAID 0 I presume is 8^2*(%break). Please run them in RAID6 at the very least, RAID 10 is preferable. RAID 0 has absolutely no protection whatsoever, if one drive goes down, the rest of the array goes down. I'd recommend simply just two Intel 520 SSDs in RAID 0 and a HDD, or an OCZ Revodrive which unfortunately though will not fit on your motherboard unless you were to go 3-way SLI, which I do not recommend.
Now, why would you go for the 3930K? Why not go for dual processor setups on the EVGA SR-X? Xeon processors are essentially the 3960X with a lower base clock but many more cores. Forget the gimmicky features of the ASRock X79 Extreme 11, dual CPU setups are infinitely better than dual PLX chips. I'm running 2x Xeon E5 2687W on the EVGA SR-X and general performance is absolutely incredible, even in things like games.
The SR-X also presents an opportunity for an even better upgrade, which is 96GB of RAM. You can easily fill all of those slots with some G.Skill and there, you have a manageable size for a RAMDisk which can be configured to transfer data to an SSD and back once you reboot, and everything stored there is stored in an instant since RAMDisks have a sizeable transfer speed advantage over a regular SSD.
Absolutely wasted potential though, unless you plan on getting 7680x1440 in the future. The 4GB of VRAM is hardly being applied here, because you aren't even using a single 1080p monitor. The new Asus WQHD monitors should be more than enough to take full advantage of those, so if you have enough cash left, I'd recommend looking in that direction. I too am currently using a temporary display until those come out in Australia.
