A:AnswerIt might not, other people have reviewed that is does no come with a low profile bracket. Look at the back of your computer, a low profile bracked will be about 2 inches in length where the PCI rear slots are on the back of the case. A standard length bracket will be about 4-5 inchs.
In the link shows what you will need to make sure the card comes with. Based on your case design you will need this low profile bracket for whatever low profile video card you get.
A:AnswerThe reason you're probably not seeing a GC or graphics card per say is because your computer is reading the on board graphics chip. Or the APU for instance. An APU is basically a graphics diode and cpu or processor combined together to make a faster chip. Or as so AMD claims. There fore the PCI Express slot usually blue colored would be empty. The slot for a GC or GPU would be located bottom of motherboard and has to have a slot opened on the slits to the rear or the case.
A:AnswerAMD was your first misstake.
1- I would replace with a NVIDIA GTX 970 or GTX 980
But if you bent on keeping it you will need to go to ASUS home page and find your card under support and then drivers and bios.
Download the newest drivers and follow the install instructions.
Then get a NVIDIA GTX 970 GDDR5 4GB and enjoy a real graphical experience.
