According to the <A HREF="http://www.asus.com.tw/mb/socket478/p4s133-vm/jumper.ht..." target="_new">Jumper Page</A> it can support a 133MHz FSB for the CPU. Now, that means it can support ALL Socket 478 CPU's. The fastest available right now is the Pentium 4 2.8GHz. At 2.8GHz, it should be able to compete with the 1533MHz Athlon XP 1800+ quite nicely. You see, SDRAM handicaps the P4 by about 30% in performance for the slower processors, and the faster the CPU, the bigger the handicap, I'm guessing 40% for the 2800+. So by getting a $600 processor, you'll finally be able to keep up with a $200 mobo/CPU/DDR combo!
