What PSU should i get??

[dk0000000]

Hi everybody, I am planning to build my first desktop, and I have made my choices for everything but the power supply. So please give me some suggestions of PSU according to the other parts Im getting.
(P.S: the mother board already has a video chipset (ATI Radeon HD 4250) with it, so can i still place the Cyclone on the mother board at the same time? Or it is crossfire?? Anyways, im thinking to upgrade to crossfire sooner or later, so do i must have the same GPU in order to do so?)

I would drop the CPU to a 955, it is the sae chip, just the muliplier is set to one less. You can bump it up to 965 speeds without causing any trouble, but you will save a nice amount of money by doing so.

I would also swap the hard drive to:

Onto the actual question though, for the power supply,
