Purchased this motherboard in conjunction with an AMD 965 Black Edition Quad Core processor and the two make for a great setup. This mobo is a real treat, has a lot of great utilities and functions for custom profiles, overclocking and more. Easy to install and setup and made for a vrey hassle free RAID array setup. Plenty of PCI-e slot spacing for going up to triple SLI or Crossfire configurations, but spacing does not really allow for a 4th grpahics card….which is overkill anyhow. Even the onboard sound is pretty decent. Really liking this motherboard!

I just built a new elite gaming system with this mobo as the backbone of it and it is AMAZING!. Great features great design and its just amazing.
Note to buyers this only allows for crossfire, not SLI.

I ordered this through Amazon with 2 day shipping and it showed up the next morning. I use this board in conjunction with an AMD PII 1090T Thuban, 4gb of DDR3, a BFG Nvidia 9800 GTX+ OC, 32 gb high speed ssd and a 500gb 6gbs pair of data drives raided together.
This motherboard is awesome, it’s excellent for gamers but is tuned for over-clocking. I have actually used almost every feature on the board and have to admit, they are REALLY useful.
Their are a couple of issues though. You MUST update the BIOS (this is a no brainer and should be done regularly) and there is a bug with Vdroops and LLC= Load Line Calibration. Right now if you turn LLC off, the system suffers a MASSIVE V-droop. IE: set the system at 1.47v and it return 1.356v at load. Turning LLC on can cut back on the Vdroop, however it also raises your operating temperature a bit and is unstable with a high overclock. ASUS is working on this already, a fix should be on the way shortly, until then you can compensate by finding how large the Vdroop is and over-volting the difference. Not what I recommend doing, but it works.
