Get the asus, it has 4 SATA channels as opposed to the gigabyte which has 2. They both support RAID. Unless you have lots of IDE devices, the gigabyte mobo offers 4 IDE channels (IMO that's a waste if you are building a new system might as well pay a little extra and go for SATA hard drives) I also like the Asus because it offers two different RAID controllers, and I'm a promise fanboy
I'm not sure what a DPS port is, however I think that's the name for the 4 pin (2x2) power connector. If I'm wrong hopefully someone will correct me (and I apologize for being incorrect). However, If I am right however, both have it, but the position for the Asus one is much better as it is near the edge of the board rather than right near the processor.
