I am trying to upgrade my small form factor pc its a Acer Aspire AX1420G-U5832 , I fell into some money troubles so i dont have much to work with i got this computer because of its Cpu which is a Athlon X4 645 but as a noob i did not notice the graphics i would be getting which is terrible and integrated . I've done some research and am under the impression that all i can do is upgrade my case ,psu and gpu as i purchased the computer for gaming which obviously it cant do i need help , i dont know how to go about getting a new case because i dont know how to tell if the Mid Tower cases im looking at support a Small form factor motherboard and i know nothing about graphics cards so can anyone recommend any cases and graphics cards . Keep in mind i only have $200 to work with possibly $250 . Im looking to play games like Black Ops 2 , Final Fantasy Games , pretty much games that are graphical .. Thanks in advance for all your help
