That depends on what you want to do. If you need a top line motherboard with the best possibilities for overclocking go for the known names: Abit, Asus, etc. If you want a cheaper mobo (still high quality) with less OC possibilities go for ECS k7vza. It is a via KT 133 based mobo for about US$55-60. You can see how it performs against its competitors at http://www.tomshardware.com/mainboard/01q1/010117/index.html. One part from the conclusion of this review was: “During the performance tests, the ECS K7VZA challenges the positions of the Asus A7V and the AOpen AK73 Pro. The design of the ECS board can, therefore, be described as a clear success. The ECS board is less suited to overclockers as it neither allows adjustment possibilities for the Vcore core voltage or 1 MHz steps for the processor bus clock nor does it allow adjustments to the multiplier”
However, there is a couple of things to say:
This mobo (in general via KT133 mobo’s) doesn’t support DDR ram.
The revision tested at Tom’s was 1.0. Currently you can buy 3.X. (better support for Athlon 1.4)
About P4, there are lots of opinions, but there is one clear fact: in general AMD is cheaper at the same performance. So if money it’s an issue go for AMD, no doubt.
Good luck
