Buying an Asus Sabertooth Z87 motherboard soon and Im worried that my graphics cards will block my PCIe x1 ports. Im getting 2 superclocked GTX 760's and Im also getting a Creative soundblaster ZX sound card along with a dual band wireless PCIe card. Will the cards block the ports? (Not getting the sound and wireless dual band cards isnt an option for me so if I have to I will only buy 1 760 or a higher quality card at the same price.)
