Neither company is top of the line and Asus has a board in the works. If I were you i would wait until a few things happen:
1) DDR Memory becomes readily available and inexpensive
2) This chipset undergoes a couple revisions if necessary, if not, proper hands-on testing is done
3) Other major manufacturers of high quality boards (MSI, Asus, Abit) makes 1 or 2 of these boards
4) Tomshardware, sharkyextreme, or AnandTech does a review of all the available 760 boards once more easily obtainable
