If I had review the CUV4X a month ago, it would have score higher. However, since that time, Abit has released the BX133-RAID which has became my favorite socket 370 motherboard, especially for Celeron IIs. Given a choice between the two, I would chose the BX133-RAID over the Asus CUV4X. This is not to say the CUV4X is a bad board, far from it. The Asus CUV4X is one for the best motherboards on the market.
If you have a Celeron CPU then I would recommend the Abit BX133-RAID over a CUV4X. For a few dollars more you get ATA100 support and built in RAID. Since Celeron CPUs are still based on the 66Mhz bus, both the BX133-RAID and CUV4X can take full advantage of it.
If you have a Flip Chip Pentium III, then the decision becomes more difficult. The Via chipset offers more compelling features over the BX chipset. The main one being the 1/2 AGP divider. This allows you to use all the bus speeds that CUV4X offers, which you will need for CPUs like that 550E. The Abit BX133-RAID really can't be use with bus speed higher than 140Mhz, because its AGP divider is limited to 2/3. Most AGP video cards won't with a 140Mhz buss and 2/3 AGP divider.
There really isn't much to dislike about this ASUS motherboard. The only improvement I can think of would be better placement of the power supply connector. Asus has always priced their boards higher than the competition and the CUV4X continues that tradition. The extra cost may be worth it however. There really isn't another socket 370 motherboard out there with such a complete feature set.
If you're in the market for a new socket 370 motherboard, take a good look at the Asus CUV4X. This board has nearly everything one could want with the one minor gripe being the placement of the power supply connector. With its large selection of bus speeds, 1/2 AGP divider and ability to make maximum use of your RAM, the CUV3X will take your Celeron II or Flip Chip P3 as fast it wants to go.
The Goods
Lots of FSB selection
Good performance
Can accommodate big coolers
Super stable at high bus speed
The Bads
Power supply connector could be placed better
More expensive than most Via motherboards
