Hey Jose, I got the P4B533 w/ sound , 845E, 5pci, ddr333, 533fsb. It should be coming in tommorow or Monday, around four days after I bought it. The company is located in Calgary Alberta, Canada.
Strangely I heard the i845G chipset has better memory performance, I'm not sure if this is true. Also, the Asus i845G is $20 cheaper. Hmmm. I guess we won't know untill the reviews come out. I will do some of my own benchmarking when I get the board.
