When purchasing a new gpu for your rig there are a few things to consider,
First, do you have the socket for it? The gpu you mentioned, as many do these days, requires a pci express x16 3.0 socket.
Second, do you have the room? Some gpu's are longer than others. Check the dimensions on the specs for your potential new gpu and then measure the space inside your rig from the pci i/o on the back of the case to the start of the drive bay cage or whatever obstruction is inline with the pci i/o port on the back of the case. You will probably need some "extra" space as well for power cables etc so allow for those as well. The one you mentioned earlier seems to have little room requirements and should fit in most modern atx cases but also note that this card, like many today takes up 2 slots so allow for that as well..
Third, do you have the power? Check the specs on your potential new gpu and see what it requires to operate. Using the gpu you mentioned we can see that it requires a "400 watt or better" power supply to operate. Also check the connection type. In this case the gpu requires 1 "6 pin" connector. Some require 2 6 pin connectors, some require 2 "8 pin" connectors etc... Make sure you have the proper connectors and output to feed your new gpu.
Those are the main points I start from when selecting a new gpu. Most modern gpus from both Nvidia and AMD can run most games and applications. The best resource for determining if you need something "above the norm" I would say check the system requirements for your most graphic intensive app or game, and use the "recomended specs" rather than the "minimum requirements" to gauge your needs.
