Workstation for numerical models and low end video editing

[xvantsik]

Good evening everyone. I am a civil engineer student and i want to build a workstation for numerical models (SPh, Smoothed Particle Hudrodynamics, mostly) and low end video editing. As pf low end i meen 30fps 720p. The budget is around 3000 euros (3350 us dollars). I ve come up with a build on my own, that has the basics with the potencial for future upgrades. Take a look:

Motherboard: ASUS Z10PE D16 WS

CPUS: 2x Intel Xeon E5-2630 V3

GPU: EVGA Geforce GTX 960 4GB

RAM: 8x G.SKILL Value 8GB DDR4 2133 MHz

PSU: EVGA 1000 CQ

SSD: Kingston SSDNOW KC400 256 GB

Tower: Phanteks ENthoo Pro Window

The above is a total of 2850 euros. Take note that i ve made a big discount on the GPU, as i am looking for a future upgrade with 2 or 4 GPUs (quadro). That is why i went with the 1000 W PSU. But do i need SLI for optimal performance in direct computing in the GPUs (with openCL). I know that wihout SLI the OS will utilize only one GPU for video output, but will the nonSLI efect the performance in the direct computing? Also i ve chosen RAM without EEC, do you think tha it is neccesary or can i go wihout it? Can anyone propose a better setup?

Thank you in advance!!!
