If you were thinking of this as being a cheap CPU for a GPU training rig. It only has 24 PCI Express lanes. It might be better to stick with Xeon CPUs because most have 40 lanes.

Thanks for that. Was thinking about building a similar build I current have which uses a 5960X for the 40 lanes.

Usually you don't need x16 lanes for each GPU. x8 or even x4 in PCIe 3.0 will be enough but there is no way to know without checking.
