I am thinking of adding a new graphics card to my build. My mother board's a Gigabyte GA-F2A88XM-HD3 with A8-7600 kaveri APU. On board graphics is Radeon R7. I am planning on installing a really cheap graphics card, Powercolor AMD RADEON 1GB 128BIT Graphic Card, which supposed to have RADEON HD6570 as a graphics engine. Searching online, I found that it requires catalyst drivers. Is it compatible with my current build and do I still need to download catalyst if it is compatible. I already installed crimson relive.
