I'm about to assemble my first complete build with an ASUS A8R32-MVP Deluxe MB and an Athlon 64 x2 4400+ (89w) CPU plus 2GB RAM. I will use 2 x 320 GB SATA II Seagate drives, so no hard drives on the IDE channels. But I'm putting in 2 DVD burners, one with Lightscribe. Anyone know whether it would be better to connect them both on one IDE channel as master and slave, or on separate channels as masters each? I expect the only times it would have any imact is when one is copying from one to the other, or when one is burning two DVD's at once.
