Mainly, I went with the Asus X79 Deluxe because it was one of the few motherboards at the time (Alongside EVGA X79 Dark) that were built for use with the Ivy Bridge-E platform in mind, as opposed to currently existing boards (P9X79 Deluxe) that would merely have bios updates. I, personally, would rather have a product that's been built from the ground up to support my chip as opposed to having the support added on.
As for the Rampage IV Extreme, it didn't have any functionality I would use that the X79 Deluxe didn't have. On the contrary, the X79 Deluxe had more SATA 6Gb/s connections than the other boards (Which I would need, as you can see from my storage configuration), and came with a couple of new features which have been extremely handy like the 4-Way Optimization feature that automatically overclocks your system fairly nicely (Got my processor up to 4.9GHz with the click of a button)
Lastly, yes, this board has Bluetooth 4.0 and AC (Newer, faster standard) Wi-Fi built in. I've used the wifi with much success, but the Bluetooth functionality hasn't worked as well for me, possibly because of all the interference as my workstation sits atop my network center.
I would most definitely recommend the Asus X79 Deluxe over any of the boards you listed (It's also cheaper than all but sabertooth, too). And unless you're going to be running the SSDs in RAID, I'd recommend getting a single Samsung 840 Pro 256GB instead, it's got the fastest read/write speeds as of now, and it's also cheaper than getting the 2 128GBs you have listed.
I'm using the 770s merely for the CUDA cores and memory, the small improvements I would gain from 780s would not be worth the increase in price. The air cooling works great on my CPU, at load it never goes above 50°C. A single Xeon E5 4640 costs $2,800, dual Xeons would cost me $5,600 alone. Lastly, two titans would be a terrible investment, a Tesla K20 would be better for my specific needs.
At the beginning, you notice a huge increase in productivity from using triple monitors, I have virtually eliminated switching tabs from the equation altogether (I'm able to do everything I need to do simultaneously)
Likewise, with the machine itself, I initially perceived a huge performance increase over my old pc. However, after using it for a couple of days you grow used to it and it becomes your new baseline. Kinda like how we think internet nowadays is slow if a video can't buffer quickly enough to stream it in HD, yet it wasn't that long ago that dial-up was commonplace.
It would certainly make a great gaming machine, I wish I had something remotely close to this back when I had the free time. Workstation-wise, I think it's pretty good performance/value. The top tier products are significantly more expensive ($2,800 for a Xeon Phi coprocessor) so instead I bleed it for all its worth, bottlenecking my components to their full capacity.
Lastly, the Uninterruptible Power Supply is wonderful. Due to the energy efficiency of the monitors/workstation, it runs at about 200W when not under load. This gives me roughly 30 minutes of runtime in the event of a blackout to finish what I'm doing and save/backup my work.
They got fairly good reviews, once I narrowed it down to a 24" 1920x1200 monitor, the candidates were Dell U2412M, Asus PA248Q, HP ZR2440w and NEC EA244WMi. From those, HP and NEC had the fewest negative reviews and were both in the same price range. I then picked NEC over HP due to the features, up to 5 monitors can be synced together so I don't have to re-do whatever changes I need to make on one monitor on all 3, I just need to change the master.
Lastly, it's got other miscellaneous features I found interesting, lowest energy consumption, it automatically turns off once I leave my desk, turns back on when it detects me again and alters brightness according to ambient lighting and white content on the screen.
Triple Monitor Stand
It's listed as the upper boundary for what it can hold, I'd say you'd be cutting it close.
Just ran a quick stress test, 78/59°C for top/bottom video card.
Needless to say, a light workload of OCR requests brings my workstation to its knees. Once I get a sufficient customer base I'll have to invest in multiple dedicated servers, each with 384GB RAM, dual Xeon E5s and Xeon Phi Coprocessors.
Again, this is a workstation. Top tier for workstations would be something like a dual Xeon E5 with 128GB RAM, a Xeon Phi coprocessor and a simple graphics card for display. If you really wanted you could add a Tesla K20 in Maximus configuration.
That is correct, I'm using the onboard raid controller.
The workstation is going to be used strictly for the aforementioned purposes. I'm using the graphics cards for parallel programming and multiple displays (hence the 4GB version).
That being said, the increase in cost is not worth what little performance boost I'd get from a 780. The only alternatives would be to go the Tesla K20 route and that's a whole new price tier.
We'll go with mid-high range, then. (Top tiers being set apart for dual Xeon workstations with 128GB of RAM)
The mouse is very nice indeed, excellent set of customizable buttons. Between the mouse and keyboard, I can pretty much do anything or open any page/folder with the click of a button.
I haven't gotten a chance to start CUDA programming yet, so they haven't been placed under much stress.
I was looking at the Dell U2412M but read some negative reviews (Mainly on the screen coating), so I went with these instead.
As for the company, it's related to health/nutrition and complex optimization problems. Hopefully I'll have everything up and running by March 2014.
I am not, the third monitor is vertical for more screen real estate when working with long documents.
Thank you! The 3TB Reds are setup in RAID1 for backup. Sadly, you can't configure network drives in such a configuration, otherwise I'd set them up as RAID5.
