The AMD760 Motherboard is the best. This chipset use special settings, which reduce information transfer time (inside the motherboard).
AMD have a new agp drivers, which increase video cards power.
AMD760 is more stabile then another DDR chipsets.
P.S. If you looking for inexpensive motherboard than I suggest Chaintech with 6 chanel audio on board. If you have a lot of money than I think ASUS is especially for you (or Epox with IDE Raid on board)
