I posted this in NFS4 thread, but it's intersting it it's own right

Hmm

Aces are getting in on the bandwagon now

A heated but very enlightening discussion has (once again taken place at the Ace's hardware forums. Our last newspost about the incompatibilities between AMD762 Northbridge and the VIA686B southbridge has resulted in some extremely interesting comments. Joe James, Tyan's Sales Director:

There is no significant cost advantage to using the VIA southbridge on a Dual Athlon board. By far the largest cost component of the chipset if the northbridge which is obvious from its 1000-pin+ BGA package compared to the much smaller southbridge. The cost delta between AMD's and VIA's southbridge is a single digit dollar number, which is no way worth the risk of using a chipset combo that has not been validated by AMD (or by VIA).

And it's foolish for my competitors to spend an extra month debugging and validating an unproven chipset pair when they could just go with the AMD north and south pair. But why should I tell my competitors how stupid they are? Maybe just to set the record straight...you're not going to save $30 by using a VIA southbridge on a Dual Athlon board. And if some Taiwanese company still wants to use it their time to market will be adversely affected. I'm very happy that Tyan has sense enough to not use Hybrid chipsets in the interest of saving a few cents on a DP board, and I just don't know how other MB companies can justify it.

Chris points out that there is about $26 difference between the two southbridges. He also states what seems to be a general consensus : " I trust AMD's southbridge over Via's anyday "
