I need some advice about a graphics card for my mates build please.
Budget is not too high -at most £200 to £250 for the card for now(its just a starter until there is a budget for a much better card) and it will be paired with a Xeon E3 1230 V3(Core i7 4770 basically) or maybe a Core i7 5820 if the funds allow.
I only know what I am reading from reviews at the moment - so forgive me for any noobish questions or assumptions!! 
I had a look through a few reviews of the professional cards,and it appears AMD has a lead for Maya and 3DS Max on the budget end,but loses to Nvidia for Blender:

Saw this article about Daz3D:

Seems to use OpenGL.
However,as you guys and girls use this software - can I have any insights into what do you think is the better hardware to choose please? 
I have been looking at the AMD W4100 and the Nvidia K620 - the mate said they will be doing more designing with some rendering on top of this(?)
Of course the other path is to use a consumer grade card - now would a GTX780 or R9 290 be better,or would a consumer R9 280 for under £150 be OK??
I read something about the viewpoint acceleration and drivers being better on the professional cards,so I assume one of them would be a better fit,even if they are using much slower hardware??
