"The performance of the Asus M3A78-EMH HDMI was very impressive. Using the new chipset eliminates the need for more basic users to get graphic cards. If the user is not into gaming or dealing with 3D environments, there is no need to get an additional graphics cards, as the onboard performs good eno

Great motherboard with tons of options and abilities right out of the box. Great price too! Hybrid Crossfire is useless if you've got a higher-end card (as it does not work). Not sure how well it works otherwise, but I hear decent things.
Great motherboard for the price. Comes with loads of extra features: HDMI-out, fire-wire, dvi and VGA out. SPDIF, audio. Great for a cheap home theatre pc. Only supports AM2 & AM2+ CPU. Documentation and adveristing state this. ASUS website though does list supported AM3 cpus. I haven't tired any to know if it supports them.
For a budget mATX AM2/AM3 board with DDR2 support, this thing packs a sick amount of value. I got it for seventy bones with an another ten back via mail-in rebate and that got me 5 SATA ports, eSATA, HDMI, DisplayPort, FireWire, S/PDIF, and support for all the latest AM3 processors.
I wish I went with the 790g chipset board as it would be more in line with the "dragon" amd system but overall this is a great board. No problems except that I can't seem to get the express gate to run even after an upgrade and setting the bios to load. Could be my config.
The Asus M3A78-EM is a well put together package with almost everything needed to build a budget PC for general usage or to upgrade an aging system (in my case). Add a CPU, 2-4GB of DDR2 RAM, a HD and you're set!
I upgraded to this from my M2N and once again Asus gave me an awesome board. This one is even better because I can grab AM3 chips and use it on this. Congrats to Asus again. Been a fan since CUSL2. Cheers!
