Ok well I have a Asrock Z68 Extreme3 gen3 mobo and I wanted to put this http://www.newegg.com/Product/Product.aspx?Item=N82E16816115072 once I need to use it. So my question is. Will I have to use one of the pci 3.0/2.0 slots or can I use the 1x slot? So what Im really asking Is the 1x slot PCIE 2.0? Sorry If this is confusing
