I just got done building a new computer for my mom and I went with the GIGABYTE GA-P35-DS3L. It's a solid board, but the IDE connector is in a weird spot. If you have more than 1 PCI device you will have to wrestle with your IDE cable in order to get it to fit.
here's what I built
Q6600 G0
GIGABYTE GA-P35-DS3L
Crucial 2x1GB PC-8500 1066Mhz
eVGA 7600GT
WD Caviar SE 320GB SATA
If I were to recommend a motherboard, I'd say get the eVGA 122-CK-NF68-A1 Room for upgrades with SLI, and supports up to DDR1200 RAM. Of course it'd be nice to know what budget you are working with
and then about 52.00 in small parts like an extra fan, some round cables, and Artic Silver. Along with a few other odds and ends.
Plus already have PNY 8800 GTX card not interesred in SLI at this time.
