Difference between KT133a - kt133 ?

[KIDO1]

hello. I bought a Abit KT7 raid with kt133 chipset yesterday for 145.00 . Today the company has the Abit KT7 with
kt133a chipset for 159.00. What is the difference and should i ship back my kt133 chipset mobo, pay extra 19.00 and get the kt133a mobo?

Thank you!
