TBREAK has reviewed the 4SDA5+ motherboard from Epox,
This is a Pentium 4 motherboard based on the SiS 648 Chipset, price is around $100 :
The 648 chipset is a good alterntive for Intel chipsets. It provides almost similar performance at lesser costs. Epox does a good job with the 4SDA5+. They bring their overclocking and tweaking technology along with adding some good features. If you're looking for a lower priced board, the Epox might be one to put on your list.
