Help with Graphics card!!

Well it seems to have a PCI-E x16 port. You can install any current graphic card based on your requirement (The titles you are playing,on what resolution and details and things like that).
You must keep in mind the power requirements of the GPU you are installing since most OEM manufactures build them up with a mediocre PSU.
Also if you have anything less than a dual core processor it will be a serious bottleneck for any current gen GPU.

Mentioning you config a little more will help for further clarification.
 


well i need something to help with some simple video editing nothing fancy just to pass by, until i get the money to build a high end pc
and i dont use it for video games i just need a low end card just for now but a decent one of course.
 
Well go for R7 260X (around 150$) if you have a good PSU (the one with 6 pin power connector for GPU,using the molex splitter might work too but your PSU must be healthy enough).

The are the specs of your Power Supply Unit?
 


i don't really know, i didn't open up the pc ever since i got it but il see and reply when i find out and thanks for suggesting that card, it seems really Good and 2gb of GDDR5 is pretty awesome.
 




Thank you so much for the help and i have one last thing to ask if i wanted to install a SSD, would it be compatible ?
 
Yes SSD is just like a HDD (just smaller in size and faster) and plugged in using SATA interface. But it will need a 3.5 inch bay to 2.5 inch bay enclosure so that tiny HDD can be fitted inside your old case. (Newer cases come with built in spaces for SSD's).
