Hi guys... thinking of buying a pre used cpu + mobo + ram... Got an offer of i7 4790 + asrock z87e itx + 16gb corsair vengeance ddr3 kit for less than us200... I was wondering.. does the z87 chipset mobo support pcie 3.0...? On the asrock product page it does state that the mobo is using pcie 3.0 slot but from intel's page it said the z87 is a pcie 2.0 revision chipset... Can anyone clarify...? FYI.. I am going to pair these set with a Sapphire Nitro+ RX480 8GB gc that supports PCIe 3.0...
