I install this card and it work as describe . the graphic be awesome and it set the resolution at 1080p automatically . just follow the instruction that come with it and you will have no problem . I put this one in a Dell Dimension 8300 that have 3.5 g of ram and 250g hd . I be a novice at computer repair , but a little research and I be able to do this . just unplug and press the power button and hold five seconds to deenergize stuff inside and you good to go . touch the chassis to get rid of static electricity , handle the new one by the edge and install . good luck !
