but 4x 1x 1x can be good if will gave the best and lest issue compared to put bridge over bridge.
if an user was need a pci for example there are many adaptor on amazon and this will made the mobo probably prizeless for the less components on it.

right now on my x5000 im using only 4x 1x 1x and im ok.
