It seems of late Intel has stolen the spotlight well away from AMD and with the performance results of not only the Core 2 Duo and Quads based on the Penryn cores, but also the new Core i7, this has really put AMD on the back foot. This however hasn't stopped them from pushing forward and while Phenom II isn't all that we'd hoped for, it certainly does have its place, namely in the low cost PC/HTPC and cheaper gaming station markets.
Boards are still coming out for the new AM3 based CPUs and since they now support DDR2 and DDR3 on the same CPU, AMD hasn't cut its nose despite its face like they did with the transition from Socket 939 to AM2. The older generation of AMD users are still being catered for this time around.
Today ASUS has sent us their newest AM3 board based on AMD's top of the line 790FX chipset paired with the AMD 750SB, the latest controller hub with all the bells and whistles. Coming in at just under 200 USD from Newegg, this board looks like it could be a winner. Let's have a look and see.
The Box and What's Inside
Package and Contents
First off we start with the package and the contents. For the base boards that are part of the ROG series, ASUS has a simple way for you to identify them on the shelves. All Intel boards use a base blue for the boxes and AMD use green; pretty simple since Intel's business colour is blue and AMD's is green. On the front there is very little info apart from the company logo and the board model number.
On the back, however, ASUS does a good job to complete the picture. ASUS puts marketing info on some of the board's primary features along with a spec sheet that is available on the website and a colour photo on the top right.
Moving along, it's time to look at the user manual. ASUS colours the manual in the same scheme as the box. The user manual is the same usual manual that ASUS provides with its high-end boards, rather large with a lot of info on the board and the included software on the included DVD.
ASUS provides five SATA data and one IDE data cable in its cable bundle. There are no power splitters included so your PSU will need to be up to scratch or you will need to buy them separate.
Lastly on the included accessories list we have two Crossfire data cables for two or four GPU operations as well as a PCI expansion cover with two USB and one FireWire port.
Now we focus our attention on the board itself. ASUS uses the same black PCB that is used on quite a lot of their high-end boards. The M4A79T Deluxe uses a full size 6 layer ATX PCB to support all of the additional features.
The layout of the board is extremely well designed. The 24-pin ATX power connector resides behind the DDR3 memory slots. The 4/8 pin EPS power connector is located at the top left of the board behind the PS2/USB tower, just above the heatpipe assembly that cools the system.
The CPU socket is extremely clean of any high rise components, which are all solid state; no more electrolyte capacitors, it's all copper. The CPU is powered by an 8x2 power regulation system; eight phases are used to power the CPU core and the final two are used to power the internal Northbridge and memory controller on the CPU die itself. The AMD 790FX Northbridge and the AMD SB750 are all cooled by an all-in-one heatpipe assembly that cools the Mosfets for the voltage regulation system. ASUS has decided to remove the older SB700 and 600 series and use the newer 750 with more SATA ports and upgraded PCIe 2.0 interconnects.
On the lower right side of the board ASUS places the six SATA data connectors that are powered off the SB750. Just above this is the single IDE port that is also run off the SB750. Unlike Intel, AMD still integrates IDE into its Southbridges.
Moving along to the rear I/O panel, ASUS puts a lot of work into this area. This one contains both keyboard and mouse PS/2 ports, FireWire, eSATA, HD Audio and digital audio connectors.
Last on the list are the expansion slots; there are a total of four PCI Express x16 slots, two blue and two black. Being based on the 790FX chipset, this board supports two PCI Express x16 slots at full speed, which are the blue ones. However, if you want to run four graphics cards, eight lanes from the first x16 slot are diverted to the first black slot and a similar process with the second set of slots to give an 8/8/8/8 configuration. For additional expansion there are two legacy PCI slots.
BIOS and Overclocking
ASUS continues to use its grey tab BIOS setup that we have seen on all of their current boards and a lot of their past boards, too. The overclocking and tweaking setup is spread amongst the AI Tweaker Menu and the Advanced menu.
The AI Tweaker menu is what ASUS uses for its mainstream boards, where Extreme Tweaker is used on the enthusiast boards. While it's not as refined as the Extreme Tweaker, we see that this board has a lot of tweaking and overclocking options nonetheless.
Under the Advanced menu we have access to the CPU Features page which allows you to set up a few of the additional features of the CPU including Cool&Quiet, C1E and various other tweaks.
AMD overclocking is not as refined as Intel's overclocking; even Core i7 has a better turn out than AMD. However, we managed to get a healthy 255MHz FSB; lowering the CPU ratio allowed us to get some extra juice out of the board itself.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.

Lastly, we see that Crysis likes the increased speed of the ASUS board when overclocking.
Power Usage and Heat Tests
We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).
There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.
The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.
So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.
ASUS uses its EPU engine to help reduce power and we see that it works here quite well. However, it's not as effective when overclocking as more power is being used to help stabilize the system.
As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.
ASUS' heatpipe assembly is extremely adept at cooling the system components.
With every new ASUS board that comes out we see them improving quality and features. The M4A79T Deluxe is definitely one of the best AMD boards we have seen with the ASUS logo branded on it. Not only does it use the high quality 790FX chipset, but it also now has the improved SB750 with additional SATA ports.
AMD may not be the highest performance processor, but its price sure does compete. You can build a competitive rig with two or more GPU's and a large memory capacity.
With a price tag of 199.99 USD from Newegg, this board definitely is a good value choice for those wanting a good Crossfire rig or a cheap AMD overclocker.
