I'm about to buy new computers for a gamecenter.
They would be used for gaming mainly.
I don't care about overclocking.
I do care about performance and stability.
I would be using a 7600GT video card.
I'm looking for a good cheap motherboard.
For what I've seen, the performance of the Nforce 4 and the 6100 is the same.
The 6100 has Sata II, and integrated video (video that i won't be using. )
I'm comparing the Nforce 4 (not ultra or sli), cause those two have features that I don't need and they are more expensive.
(In 70 computers every dollar counts)
The Asus is a known, stable mobo that's widely used in SOHO systems.
Foxconn is a lesser known brand that supplies many OEMs.
The EpoX in nF4Ultra form is widely used reliably by budget overclockers.
I believe that all 3 of these are good candidates. Google for reviews any that interest you, but info may be hard to get. Most people who use these boards don't know they have them.
The most likely culprits for instability in the boxes you build will be the quality of the power-supplies used and the cooling effectiveness.
I highly recommend adding a cheap intake fan in front of the HDD on the cases you use, and consider the following high-value PSUs:
