Our Land Surveying company has just started to delve into the world of Reality Capture, Point Clouds and consequentially 3D CAD Modelling. Our "IT" guy is a family friend of one of the directors and I've always been skeptical of his true knowledge when it came to the requirements specific to the CAD work and data processing we do. A recent job we have acquired is now in its third month of data capture and modelling and our current system were no longer being able to efficiently manage the data sets, especially when it came to 3d modelling in Autocad 2015 and creating rendered viewports for presentation. "IT" guy is brought in to upgrade my system, I explain to him what I do, show him the current issues with lag and render times when panning and viewing the model and he goes off with a $5000 budget to play with. 2 weeks later he comes back with a car load of gear, spend a night putting it together and I get to work on it the next day.
Through my own knowledge and research I knew what ideally was needed for an efficient machine. And with $5000 to play with I assumed "IT" guy would know too. Heres what I ended up with
2x512GB Marvell Raid 0
Intel i7 4820K @3.70Ghz

and heres the clincher

2x AMD R9 290X GPU cards

now with that kind of grunt I'd expect it to run remarkably faster even if they aren't specifically Workstation Cards. but I am not seeing a difference which is allowing me to maintain a workflow that isn't hindered by render times when working with the model.

So are the drivers for these cards really only specifically for gaming? and the main question is should I sell the 2 cards and replace them with Workstation Grade cards and if so which one/ones..? thanks in advance for your help.

Consumer graphics cards benefit from DirectX optimizations, Autodesk is unique in they take advantage of this. AMD's Radeon R9 290X holds its own in 3d rendering but the results are not always the same. There is a bit of a stability issue to be concerned about with consumer level drivers in business oriented rendering. Lets look at it this way do you want to pay 10K for a Autodesk license and loss 100 hours of work due to a IT guy installing a piece of $500 piece of hardware that May or May...

Do yourself a favor and invest in what is approved by your license and eliminate the "???????" factor because in business rendering you want 100% assurance.

thanks for confirming and reiterating what I thought about the whole thing. Autodesk doesn't have approved and certified GPUs and respective drivers for no reason but when I brought up Quadro cards, 'IT' guy brushed me off in a very obvious 'I don't actually know what that is but theres no way I'm admitting that to you' kind of way. As only a medium sized surveying firm the short term benefits of overhead cost cutting are always appealing. Hence the quotation marks around 'IT' through the thread.
 
Autocad uses dx but recap is opengl. I'm not familiar with reality cap or point clouds but afaik from googling they don't have gpu acceleration and none of these software uses 2 cards, they only use 1. Depending on the timeframe as the new 2011-3 cpus came out aug 29, he also got last gen cpu and getting a quad core on lga 2011 only makes sense if you need more than 32gb ram.
