And do not use an Intel CPU.  

Intel only has 4x PCIe lanes that are shared out into whatever
configuration they claim to have and are totally unsuitable for use in
a computer that actually has to be able to do high-speed I/O.

That's likely to be incorrect. Intel CPU usually have 48 lanes for the
Skylake generation. The 4 lanes limitation only applies to what is
connected over DMI to the PCH, which is usually used for low-bandwidth
stuff (1G NIC, SATA, 1x PCIe slots). Look at your motherboard manual to
check how many lanes are affected to each component.
