Rx 470 with 6pin vs 8pin overclocking

[p2345]

So I'm looking to buy a new graphics card and I remember all that buss that happened to the rx 480 and the reference model with their 6pin, etc, etc.

Looking at the 470, the model is pretty similar to the 480, most reviews put the power consumption at 130w under load. So, if I bought a rx 470 with 6pin and wanted to overclock wouldn't I hit a power bottleneck? Does the card throttle the boost speed during load like the reference model?Would be safe to crank up the power before OCing?

I have a decent PSU I guess, it is a XFX 650W TS and I would like to play with OC a little, but I'm not sure if the 6pin might hurt the performance or it doesn't really matter.

It would not hurt the performance, but:
1) generally power limit for OC is likely to be set lower for RX470 with 6-pin than one with 8-pin.
2) whatever power limit is set- it can be taken, even if it is over 150W. Depending on model, bigger part of power can be taken then from PCIe slot, or 6 from pin, or, most likely, equally from both. That would put load on PCIe at ~75W which is acceptable if your motherboard is good, but generally it is better if card has 8-pin connector, and is set to take bigger part of power from 8-pin.
