As usual most of the prices went down, between $1 and $20 since the last update of the lists. The only changes were updating a few of the motherboards and the recommended DVD burner. AMD is set to release the new Bulldozer CPUs, which will run on socket AM3+, very soon. We changed out the AMD motherboards to the socket AM3+ equivalents of the socket AM3 motherboards that were in the lists. The LG burner that was in the lists has been discontinued. We replaced it with a burner from Asus.
