Abit AX78 Socket AM2 Motherboard
 

The Abit AX78 Socket AM2 Motherboard is based on the AMD 770 / SB600 chipset and supports the AMD Dual and Quad Core processors. It accepts up to 8GBs of Dual channel DDR2 1066/800/667 un-buffered non-ECC memory. This motherboard also comes with passive cooling using just heatsinks and a heatpipe, so it's completely silent. It's also Crossfire ready, has 7.1 CD HD audio, RAID controller and much more. This motherboard has major bang for the buck.
