Well, I could pick out some real expensive merchandise that I'm sure will work but I don't know if that would be what you want. You should give the budget amount that you want to have and whether you want AMD or Intel.
Since your setting up Crossfire you will most likely be gaming and want an Intel cpu.

I don't know if this is high end enough for you and I can go higher if you want.

since you are only going 2 way xfire this may be more appropriate and will be fine for overclocking:

Also, keep in mind the the Maximus is E-ATX and will only fit in a few cases.
The i5-3570k (and the older 2500k) are the gold standard in gaming cpus.

It wasn't an actual recomendation since the op didn't give a budget and I was more showing what can get suggested when you don't give a budget.

thanks for the info guys! i was wondering if Corsair 9-9-9-24 1333 ddr3 ram will work in that MOBO Inzone listed. whats the deal with the #-#-#-# and the 1333? higher means better?

also, ive got a 950 watt power supply. is that enough for 2 HD7950s?

i have another question about over clocking, there is a catalyst progam that came with my video card that gives the option to overclock and boost fan speeds.. any suggestions? i remember years ago hearing stories of people melting there CPUs

im also planning on purchasing that mobo and cpu that you listed Inzone, any other suggestions?? im going to need a new tower to fit all of these new toys

is it easy to install a CPU to the board? i know how to apply thermal paste but thats about it when it comes to that. is there a youtube video you would recommend?

The MB lists the ram that will work with the board and certianly 1333mhz will work and so will 1600mhz which is what would be a good choice. The 9-9-9-24 numbers are the timmings of the ram and higher is not better , lower is. So if you got 8-8-8-24 would be better.
The 950w psu would be enough to run what you want.
The overclocking of a gpu would not be very necessary in your case with two 7950's you will get plenty of performance. If you wanted to boost the clocks some you could but you wouldn't need to go crazy. Melting the gpu would be if you added too much voltage to it when overclocking.
It is relitively easy to install a cpu into the MB socket , you just have to be extremely carefull not to bend any of the pins in the socket. You will never get them straight again and the board will be useless. Follow the instructions in the MB ownersd manual and you should be fine. You can also Google a youtube video on installing one.

A case is more of a personal choice and as long as it has good air flow if you come across one that catche your eye then you should get it. You also have to decide if you want full tower or mid tower and how much you want to spend on it.

So I bought that mobo posted, mounted in my tower and now putting everything together... It seems like there are alot of pins still sticking out that should have power. How come there is a 4 pin at the top and another 24 pin by the ram? What else should be getting power beside the easy ones like the rest of the hardware.

This is my first install by myself and I don't wanna start anything on fire lol
