I am responsible for purchasing a pc build that mimics a pre-built pc on TigerDirect. I am using the same processor (I5 3550p) which does not have integrated graphics. I also have purchased the Asrock Z75 pro 3 mobo and it, like all the others, says onboard graphics supported only with cpu with integrated graphics. I need to know that I can use a Non integrated graphics cpu and just install a graphics card of random quality for basic video and it work? This would be a video card installed in the pci x16 slot as well.
