I don't think there's a definitive answer to this as there's a lot of deciding factors such as what you intend to actually use it for (CAD, 3D software, gaming, etc), budget, power requirements, monitor support, etc

From the specs listed the system can take a full-height PCI-E graphics so either a GeForce (Nvidia) or Radeon (ATI) card will be a good start. The machines only seem to have a standard 320W power supply so you may need to upgrade this depending on the card chosen (some can take power straight from the motherboard, others require additional power connectors).

It's also personal preference - some people prefer ATI over Nvidia, personally I favour Nvidia.

Agree with all the above.  May also need to consider how many monitors it supports, as well as their connection types.  Support for 4 from a single card is possible, but I wouldn't use it for gaming...

This is a decent comparison site:

Also need to consider the screens you have in mind as well.  No point buying 4k screens if you don't have a good card, and not much point buying a ninja card if you're stuck at 1024*768...

maybe you can use the GTX750 :   http://www.anandtech.com/show/7888/best-video-cards-march-2014

 the GeForce GTX 750 Ti, a card that offers performance approaching the R7 265 with much lower power consumption. The GTX 750 Ti is a sub-75W card – no external PCIe power connector required

calculate here that you don't exceed the power rating of the PSU : http://extreme.outervision.com/psucalculatorlite.jsp

The memory size is only one part of what makes a decent card.  If you're doing a lot of CAD work or photo retouching, then the GPU *speed* is equally important.  Admittedly, high-end GPU cards tend to have a lot of memory too, but not necessarily.  Why is 4gb so critical?
