HI I'M LOKING TO UPGRADE MY GRAPHICS CARD TO ATI RADEON HD5450 1GB DDR3 PCI EXP 2.1 IN MY AMD ATHLON II X2 250 COMPUTER WHAT WOULD I NEED TO DO
Well, its likely you have a pci express slot for a graphics card but not guaranteed. We need to know more about your system to verify this. Who is the manufacturer? Model?
Also that is a low profile card so it should fit many form factors, including micro ATX. It is not a very fast card however, not much of an upgrade from integrated video. Have you researched this card?
