Is this Mobo ok for my system

[BlizzardSSE]

Building a PC with the following

i7 950
2x Radeon HD6870 CF
4GB 1333 Memory
500GB Hard drive

Been looking at the MSI X58 Pro E and MSI X58M. I will not be overclocking at all so just need something that wont hinder my performance.

And one last question (sorry this doesnt quite belong here). What power box would I need for this system? I was recommended a PSU of 650W on this forum; however, I have since read many reviews on i7/crossfire systems and most use at least 850W?

Thank you

Unless you already have bought the parts I would reconfigure your choice with the new Intel processors, not a i7-950.

They offer better performance for less and the motherboards and ram are cheaper.

Oh and a quality 650w is more than enough for crossfire.

1) The i7-950 will perform exactly the same on any X 58 motherboard. Even if you want a modest overclock,(and it is easy) any X58 motherboard will do the job.
The MSI X58 Pro E will do the job.
2) For 6870 CF amd recommenda a 600w psu with 4 6-pin pci-e connectors:

The XFX 650 would be a good unit, modular and inexpensive:

Nothing wrong with 750w or 850w. Look also to Seasonic, Antec, Corsair, and PC P&C for a quality unit.

You really ought to be looking at a sandy bridge cpu.
They are faster than the i7-950 at stock, competing with the i7-980X in some benchmarks.
Clock for clock, they are perhaps 15% more efficient.
With 32nm construction, they run cooler.
A P67 motherboard will cost you less.
Two 6970 cards will not saturate the two X-8 pci-e slots, so that is a non issue.
I suggest the 2500 if you will never OC, and you really won't need to. It is shocking how good these new chips are.
Still, I suggest the 2500K because the price premium for OC capability is so small.

If you can, add in $100-$200 for a SSD for the os and apps. It is one of the best performance buys you can get. You won't regret it.

If you don't overclock, the i5-2400 is only $175 after promo code right now, that's $20 off and $50 less than the i5-2500K which is only 100mhz faster.

Even though it's not unlocked, it will still overclock to 3.7-3.9.
