Hello I want to build a new computer. I'm not a gamer just want a decent setup. I have an Intel i5 4670 processor and a asrock fatal1ty z87 killer motherboard. Can I use this board without a dedicated graphics card
Yes, it will use the integrated graphics on the i5 4670. Graphics won't be the best if you are gaming, but for general purpose use, the integrated graphics should be fine. For gaming, you will probably need to spring for a dedicated GPU.
