Motherboard for my components

What are you doing on the PC, if it's for gaming and the usual stuff you don't need more than 4GB of RAM. Better get a 6870, it's cheaper and scale better in CF. You can
For crossfire you can get the Asrock 870 Extreme3, Gigabyte GA-890GPA-UD3H, Asus M4A89GTD PRO/USB3.
I think the Asrock should be better for CF due to the bigger space between the two PCIex16 slots -> less heat.

I too am buying a Phx4II 965BE. Asrock is not a brand that I would go out on a limb for and trust. I am unfamiliar with them.
My top M/B manufactures are:
1.ASUS
2.MSI
3.GIGABYE
If it helps, I was planning on purchasing
ASUS M4A89TD PRO/USB3 AM3 AMD 890FX $174.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131655&cm_re=890fx-_-13-131-655-_-Product
Im not asking for help. Im clearly stating that I disagree with the suggestion of the Asrock motherboard. I also offered some insight as to what I would have chosen due to my similar circumstance.
For me, the ASUS M4A89TD 890FX is a perfect match. You may have a different preference.

Hmm... with CF HD 5870 => ASUS Crosshair IV Extreme AM3 AMD 890FX SATA3 USB 3.0 http://www.newegg.com/Product/Product.aspx?Item=N82E16813131667 otherwise you've got your priorities wrong with $600 in GPUs on some run of the mill MOBO and your choice of CPU in CF of those cards is 'odd' as well. I would recommend the AMD Phenom II X6 1090T Black Edition. BALANCED...
Why the mixing of XFX and Sapphire? Don't get me wrong, I know do it will work - just seems odd. Also, there's NO WAY 650W is going to power CF HD 5870's ---> 1000W is needed to OC both the CPU + GPUs; 850W with NO OC'ing minimum!

Well I bought the xfx 5870 new then got a really good deal on the sapphire thats why the mix, and this psu has been powering these two gpus for months now just fine, I have that in another post. The board you recommend is nice but overkill for what I need. I have also been overclocking both gpus with ccc all this time to no probs! any other mobo suggestions! thanks though!

Let me know how that PSU works for you in a few months 
I never recommend overloading a PSU and I would assume the PSU is running hotter than hell under load while spinning the fans @ 100%. If none of that's 'true' then they mislabeled your PSU.

Hey you can build it anyway you'd like, it's nothing I would do. Tom's H/W posts GPU centric builds with no thought of 'balance' thereby convincing people to do the same. For them it's a Game to have the best bang for the buck with ZERO thought of longterm consequence. People like me who do build high-end rigs know better and advise people correctly.
Again, $600 GPU CF HD 5870 - #2 choice ASUS Crosshair IV Formula, #3 Choice ASUS M4A89TD PRO/USB3

PSU - Run Futuremark or Crysis for a while and tell me all about it then.
This is the most conservative PSU Calc {read the caveats on the bottom} - http://www.thermaltake.outervision.com/Power
@nfuzer then what PSU calculator 'do you' recommend? When the OP burns-out their PSU in a ~year then they'll know why...
The typical load for the OP's OC rig is 580W~615W; assuming the OP isn't lying.
"Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a PSU will slowly lose some of its initial wattage capacity. We recommend you add 20% if you plan to keep your PSU for more than 1 year, or 25-30% for 24/7 usage and 1+ years."
Bottom-line, I couldn't care less - it's not my rig.
When it gets bad then it can take out the GPUs or MOBO like it did with this guy's. He did the same 'brilliant' thing.

@ jaquith you have a point. PSU's degenerate wattage capacity over time.
@minix69 if you are willing to risk your $XXXX rig for a $1XX psu upgrade, that is on you. Although you may not need to upgrade the PSU immediatley, you may want to consider upgrading it in the near future.

I really appreciate your advice I'm lookin at a 1000w psu now but the thermaltake adviser said 535w and 20% over that is 642w, but i see your point if it looses power after a while thats not enough. It just sucks because i had psus in another post and this xfx 650 is what was recommended by everyone in that post for my setup, I just bought it, bummer!

^Yeah, then factor in OC CPU + OC GPU; if you do as stated "I OC" both then what do you want me to tell you? A lie or "good advice"?
My objective is to give you good advice based upon the experience I have, and guide you in the right direction.
Personally I only like very few PSUs, and for the $ Corsair is tough to beat; you REALLY want: 1. Japanese capacitors, 2. Single Rail, 3. Voltage protection incl over/under/fault/etc. I 'use to' have a more cavalier approach until $30X2 'savings' on two Antec PSUs cost me $600 in blown capacitors on my ATI GPUs both within 30 days of each other. Then I did some research to track-down the cause and to my surprise it was my dumba$$ choice in cheap PSUs. On my everyday rig I have Corsair 750W where 600W is sufficient and the typical use is ~250W at the outlet. These are work i7's and I provisionally powered for 2-WAY and wanted to stay within the ideal 50~60% load range which is the most efficient for the PSU.

I plan to pull the second gpu though I have it sold, will my psu be ok then? or should I still get another I was looking at corsair I'm following your other recomendations as well i want the Phenom II X6 1090T Black Edition and the ASUS M4A89TD as well, with one 5870 my psu should be ok, right?
