At stock speeds, the 125W will probably be the better buy (if you're not concerned with power usage) because the higher TDP ceiling means that more cores can be activated to the turbo speed. The 95W version will likely not have the same headroom, and may only let one or two cores scale to the turbo speed before they all throttle down.

As for overclocking, that's yet to be determined. As all FX series will have an unlocked multiplier, unless the higher end models are much higher binned, it would seem almost foolish to me to spend the extra on an 8150 vs an 8100. But, we'll see when they come out if the 8150 has higher overclocking headroom than the 8100 and 8120.
