Note that due to high power consumption, overclocking on the 955 should be done with a motherboard with proper 125W support and overclocking friendly (quality 4+1 phase with cooling at the least).
I have a Asus M5A87 motherboard and i think you know that, but here is a quote from they're website.

Code:
AMD 140W CPU Support

I think it should be enough as you said it
Thanks to all posts

It will be enough to run the 955 at stock. The VRMs must be properly cooled for overclocking. With most aftermarket tower CPU coolers, this is not possible as no air gets to the VRMs and no heatsink on makes for inefficient heat transfer to surrounding air. As each component in a 4+1 phase vs. a 6+2 or 8+2 must handle more current, it may easily overheat or overload, causing (on ASUS boards) protective CPU throttling to reduce VRM power load for short (or long) periods of time, which may cause reduction in performance during full load scenarios. The issue is not to be underlooked, and it's best that you know about it

So i won't be able to overclock ?

No, I mean that you WILL be able to overclock, but you may not get reliable full 100% CPU load operation unless the VRMs are properly cooled. This can be done inexpensively.

How ?

use ramsinks then put a fan over them.Something like these:

i use them on any spare space i can (that gets hot,obviously)
or even better,this:

or put the vreg section under water
orrr mutilate an old dead board with heatsinks over the vreg section and stick the heatsink over your vreg section.
i should think theres plenty of dead old hardware that could be donated on this forum.
