Dell Precision T5810 Core options and GPU config? Running CC on virtual desktops?

Question

Hi, two questions really but didn't want to start multiple threads.
I tried searching for answers to my questions but was not very successful so am trying to post. I am looking at buying some computers for our office which will be using the CC subscription for their workflow. Predominately this is short form video editing on Premiere (3-10min, AVCHD & DSLR mix, 2-3 camera steams, 50/50 just as straight streams/multicam), some light to mid graphics on After Effect and Photoshop then compression through Media Encoder.
Our media will be stored on a Small Tree shared storage server across a dedicated gigabit network.
As Dell have just launch their new workstations using the new version of the Xeon 16 series with DDR4 RAM I was thinking of going down that road. Would I be better getting the Hex Core 1650v3, 500GB HDD, 16GB DDR4 2133 RAM with either a Quadro K2200 or Firepro W5100, or Quad Core 1620v3, 500GB HDD, 16GB DDR4 2133 RAM with Quadro K4200?
As I understand it is important make sure systems are balanced between CPU, GPU, RAM and discs. Which of the above configs would perform better for our work, as I am not sure if the hex core will be more so with a lower GPU, or if the quad with a faster/more expensive GPU will perform better?
I know when it comes to GPU's a kick off would be to say ditch the workstation line for a GTX to save money, but we have a business deal with Dell as a business their 3 year support is an important consideration to us something they do not support if we chop and change out unsupported components such as a GTX card.
The other option I have been made by our IT department is that we could buy Dell servers, add graphics cards and run virtual desktops for the editors on them instead of buying stand alone towers. I have not really seen this being done before for video editing which suggests to me that this does not work for one reason or another, but I have not been able to find out much with my Google-fu (which again is probably a bad sign). Is this as bad an idea as I am assuming or is this a potential avenue.
Hopefully that has all made sense and apologies if I have not followed any forum etiquette, (first time so be kind!)
Thanks in advance for all and any help.

Hi,
Thank you for the replies. Having looked at the virtual option more closely I have discounted it as an option. Was never really something I wanted but our IT insisted I evaluated it as part of the process.
Regarding the workstations I had decided to go with the hex core E5 1650 option so it is good to hear I am heading down the right road! My reasoning for look at the new T5810 (DDR4 RAM) over the previous T3610 which had the 1650v2 (DDR3 RAM) was based on the fact the the cost difference on the website was only about 70-80 pounds. For that little difference it seemed like a good idea to buy the latest offering for future proofing. I will however get Dell to quote me for the two systems and see what the end result is after adding in 32GB of RAM.
I will also speak to them about their warranty as I was under the impression that by putting a non approved card in the system that if there were issues that involved the card in anyway then they would not assist. Either way I had decided to go Nvidia after reading up about the Firepro computability. Sadly I don't think I would have budget for the K4200 but the K2200 looks like it might be a decent performer as it is based on the maxwell architecture so I would expect it punch a bit above its weight. Would this act as the bottle neck in such a system or would it be fast enough to balance out a E5 1650 and 32GB RAM?
If it is only the card itself that will not be supported then I guess this is lesser risk and I could consider a consumer card. If I did go down the GTX route then looking at the price of GTX 770 (ideally I would want the 4GB version as the 2GB could be limiting for the future), there does not seem to be a lot in it between them and the GTX970. I would expect  due to the maxwell architecture that this would offer better performance at a lower power draw so I would expect the be better temps than the previous gen. If so then would this be a better option to go for?
For drives I will look at putting the media cache onto separate drives (we currently do this with our systems that run local storage), though will probably have to be HDD rather than SDD as I have them spare and fast running out of budget!
Thanks again for all comments.
