I'm building a pc with an intel core i5 3750k cpu. I was told that I need a 1155 mb. He also suggested a z68 series one. Seems good enough. My question is. Some mb come with integrated graphics right? Or is it the cpu that has that. Anyways I want to but a graphic's card for this rig. Can I buy any z68 mb and get any graphics card I want. What if the mb has integrated graphics on it can I still use a gpu? Any recommendations on a cpu and mb? And ram. He said to get ddr3 what the best ddr3 ram I can get. I've seen some that is ddr3 1866. Is this the best and can I use this. Anything will help. Thanks a bunch
