i would get the asus or the gigabyte isent that the msi board hardocp reviewed here? i got the impression it was a little flakey. still here one to many bad things about msi boards to try them out.
My vote is for the Gigabyte 790FXT board. I'm current running the same in AM2+ flavor and it's an excellent board. Only negatives thus far are 1) one of the PCI slots is covered when crossfiring and 2) the voltage modifier for vcore is in .025 increments.
Haven't had a problem since the first boot, its been on for probably 2 weeks straight (knocks on wooden desk).
I suppose it is also worth mentioning that I was able to unlock the fourth core of my 720 by turning ACC to "All Cores", but I disabled it (better safe than sorry). I am sure overclocking and unlocking will be no problemo with this board.
I'd say the ASUS is the best pick. I've been happy with my Gigabyte 790FXT, but I am planning to replace it with a Crosshair III. To me, the ASUS seems better optimized, lacks all the useless crap like dual lan and the horrid JMicron SATA controller, and to my eye is much better looking (if aesthetics matter to you). It comes with a very nice X-fi based sound card as well.
Currently using the MA 790fxt UD5P on a setup where i run Age of Conan have the cpu overclocked 720 BE from 2.8 ghz to 3.6 ghz and it keeps on going.
I bought OCZ low latency ram which means im running 4 gb ram at 1600 mhz Cas latency 7.
Out of most reviews i have seen (im a news poster on another website) it seems that the reviews for the gigabyte MA 790fxt UD5P are very positive and i think it already won several shootouts on the AM3 platform.
Well if you are not planning to use crossfire right away, I would suggest getting a much cheaper Gigabyte 770T board. It would overclock within 50MHz of Crosshair III for just $85 on newegg.
I prefer the layout of the Gigabyte or Asus, just for the ability to add a PCI-E 1x card without interfering with the airflow to the GPU(s).
Currently running the Asus 790Gx, pleased as peas with it.
