Biostar M7VIB mb

[Diablo]

Been doing some price comparing online on this MB & i keep seeing different versions: M7VIB-A & M7VIB-PRO. I noticed that on newegg (http://www.newegg.com/app/ViewProduct.asp?submit=manufactory&catalog=22&manufactory=1442&DEPA=1) they have diff prices & they come in diff boxes. Anyone know the differences or which one is "better" ?

AMD (http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_869_1073^4319|61_1,00.html) lists 2 diff versions of this board, but doesnt indicate which is which. One is only recommended up to 1000 Duron, but the other supports Athlon XP 2100+

Only diff i can find so far is the following:

(M7VIB-PRO)

Sourth Bridge
Chipset Name: VT8233A

(M7VIB-A)
Sourth Bridge

Chipset Name: VT8233

Can anyone determine which is which?

On a local business website here the M7VIB-A is sold with a AMD ATHLON XP 1800+ processor, so this is what you'd probably want.
