Doesnt matter, avoid Abits. Check Anand's reviews, they never get high marks or praises. The thing is they're unstable/unreliable and low quality. The resent BX133 round up winners are what I recommend, MSI BX Master, or Asus CUBX. Abits just cant match them. If you want AGP4X and overclock to 133MHz, you might want VIA AP133A chipset motherboard, I recommend Asus P3V4X, winner of Anandtech's Editor's Choice Award.
