The 845PE is the way to go now. The 845PE has 4:5 and 3:4 mem ratios and doesn't have the integrated graphics core like the 845G did. The 845G boards were good, but did have some odd problems when overclocking that the 845D/E boards did not. It seems the integrated graphics core lowers the overclockability.
Once Granite Bay is here, no one will care about single channel DDR boards anyway.
