First time Desktop builder

So I am planning on building a new gaming desktop. It is going to have a I7 930 with two crossfire ATI 5850s. I just need someone to help me confirm that all parts will work and are compatible with one another.

Here are the parts:
Full Tower Case:
Power Supply:
Graphics Card (two of them in crossfire):
Harddrive: it is going to be some ssd/hd combo thats gonna have win7 boot up in the ssd.

First off, will there be any compatibility issues with this configuration and will I have any problems putting it together?

Second, are there any unnecessarily expensive items that I have included? By this I mean the motherboard. Can I buy a cheaper mobo that also has LGA 1366 with at least one 6gb/s sata port and supports crossfire?

Third, does the power supply have enough wattage to support the crossfired 5850s and I7 930 with both overclocked? And will it have enough amps at +12v to support the crossfire?

Lastly, thanks so much to whoever deals with this question. It's a pain to go through all the configurations and check them. I have already done all the research and double checked and they all seem to work out. But I am inexperienced and want to make sure everything is compatible.

Recommendations and Assurances

Sorry it took so long to reply; yes, it does a bit of time to make sure everything is compatible.
Here is the link for the 'Recommended' power requirements for running crossfire with 2 x HD5850's, Corsair suggests a minimum of 950 watts, but this is just the basics (2 x GPU, Core i7-930 CPU, 2 hard-drives, slightly overclocked on both CPU and GPU)

There is another person (in the 'Computer Help' forum that's having problems with his P6X58D Premium motherboard,;forum-threads)
Here is an alternative to your choice: ASUS Rampage II Extreme
(this board will run crossfire or SLI, and comes with a SupremeFX X-Fi Audio Card), here's the ASUS link to have a real good look at it

Computer cases are of a personal choice; you want to make sure that the case you choose will: a) fit all the components you have bought. b) be easy to work with-don't want a nightmare causing case, that's a pain in the **** to fit components into. c) will have great airflow. d) If your running a 'gaming' system, then you'd sooner have a case that is black inside (with a window), but don't want to have to break the bank to have one.

When you click on the link for ASUS, download the QVL list for memory, this will list all the memory that is compatible with this motherboard.

Note: Not knowing what your budget is for this system, I had to guess that you wanted to have a system that is: a) upgradeable b) reliable c) won't break the bank account d) will last more than a year or 2.

thanks for the help. I am currently looking for a higher watt psu and I am probably going to switch to the motherboard you suggested.

buying A PSU

when you're shopping around for a more powerful PSU; it always makes sense to use a PSU from reputable manufacturers (Corsair, Antec-though they don't make too many modular PSU's, Thermatake, Silverstone, Zalman, CoolerMaster)
Here's an excellent 1000 watt PSU from CoolerMaster (5 star ratings only), and it's only a few $ more than the PSU you were considering.

unless you're doing professional work

and using an 30 inch monitor, you're spending too much.

a core i7-860 is faster than an i7-920. you get can get a top-notch lga 1156 based mobo for $170. a single hd 5870 can handle practically any game on a 24" or smaller screen and even deals with most in dual 22-24" monitors in eyefinity mode.

so rather than blow $2K, start with a $1200 PC and continue to upgrade it every 12 months. today's dual 5870s will be surpassed by something this christmas at a lower cost.

yes, you're right...

another card may surpass the HD5870 by Christmas; but only by price, currently the only card that competes with the HD5870 is the NVidia GTX 470

upgrade later

so im thinking about buying a single 5870 and buying a second later when the price drops

would that be a good idea

I have heard

I have heard on many occasions that is always better to have one really good videocard, rather than having two semi good cards, so that is what I would do

5870 it is then

ill prob go with the single 5870 and then buy a second later after the price drops...

How will you deal with BIOS?
