Budget graphics card

GhostPrime: It's difficult to tell without actually seeing the board in person, but it does look to be either a BTX, or Mini-ITX board. A case may be the best way to go, and it may give more room for a GPU, (a 750ti looks like it'll fit) as well as a place for the HDD,and a new PSU.    That does open a can of worms though, that's a fair amount of work if you don't know your way around a PC to well.
