I recently made this computer without a CPU with integrated graphics. I just have a regular CPU (which is a AMD Athlon x4 860k) , and when I use my Geforce GTX 760, nothing shows up on the screen for me to download the drivers. Right now I'm using this very cheap graphics card, and when I download the NVIDIA program for the drivers for my 760, it says it can't find it in my build. My mother board only has 1 PCI-E slot btw.
