Here we explain how to know if a graphics card will fit in your PC and if it will be compatible. Many PCs rely on so-called ‘integrated’ graphics which is either a chip on the motherboard or one built into the CPU itself. Other PCs have a ‘dedicated’ graphics card, which plugs into an expansion slot on the motherboard. You can usually tell which type your PC uses by the location of the port you use to connect your monitor. If it’s in among the other ports, such as USB and Ethernet, then it’s integrated graphics.
