My pc mainly used for financial analytics work, due to the nature of stock market, the process involved a lot of small read write during the process and it took 6+ hrs to complete all the calculation daily. I am planning to upgrade my current storage to RAID 0 to speedup the process.

Current PC setup:
i7 5820k
Asus X99-II
AMD R9 270
Plextor 250gb SSD

Plan to upgrade:
nVidia GTX 1080
HighPoint SSD7101A-1 NVMe RAID Controller
4 pcs Samsung Evo 250gb PCIe M2

My question is, 5820k only 28 pci bus lane design, the display card & RAID controller together need 32 lanes, so will I getting the I/O speed I expect after the upgrades?
Do I need to upgrade the CPU as well? The analysis process itself actually don't need more processing power, worth it just because I need a 40 pci bus lane CPU?

a $800 GPU is not going to help, unless you intend to play some Battlefield 1 at 4k in your spare time...; instead of risking a RAID 0 failure and all loss of data, allocate the GPU money instead towards just one or two standard 960 Pros of the desired size (the Pro series are intended for and warranted for 3-4 times the write cycles of of the 960 EVO...) The 970 Pro is releasing very shortly, capable of 2100 MB/sec sequential writes, and with 5 year warranty) If one is not fast enough, the MB has onboard RAID 0 support for a pair. (Diminishing returns past that point anyway, unless you *truly* feel you need 11 GB/sec of storage throughput via the Highpoint RAID card)

Math calculations are rarely storage bandwidth restricted, and it'd...

Math calculations are rarely storage bandwidth restricted, and it'd be very hard to say a given system is bottlenecked by even a single NVME drive...unless you have lots of 40 GBe connections to assorted servers in your office...

Even with just 2x PCI-e lanes available for an M.2 NVME slot vice the normal 4x, this will still support 16 Gb/sec(2 GB/sec) of storage traffic...
