I'm waiting for my new mobo and RAM to arrive so that I can upgrade for a third time in 3 weeks. In the meantime, I'm upgrading someone else's system. He's going from a K6-2/300 @ 333MHz to a Duron 700 @ 1000MHz. I'm also installing a new 20GB HDD as the Master on IDE 1, keeping his old 10GB HDD as the Slave on IDE 2 and installing a new 16/10/40 burner as the Master on IDE 2.
