Here is hat HardOCP had to say about the mobo:
Conclusions & Delusions:
Well, my first thoughts about any KT266 mainboard lately have been not good at all. In fact, I have a hard time believing all the hype surrounding the chipset. Am I supposed to believe that it took VIA almost a year to make a true DDR chipset work? ALi did it, SiS is doing it, and VIA already has working P4 DDR boards. I have a feeling that the KT266 has worked all along, and they simply did not want to stop selling KT133 and KT133A because of the great yields and profit being made...OR! There is another good theory that I have on it. The KT266 chips we are seeing now are supposedly unrevised (like the one on this Asus board), just the same ol' KT266 chips that have been around for a while now. Then why all of a sudden are they working flawlessly? And if those old ones are working so well (the "CD" chipsets), then why are we going to see an enhanced "CE" version very soon? Anyway, I know I am off on a tangent now, but there have been some things going on around the KT266 chipset that are simply not right. There are a lot of factors here that we are simply not aware of. Believe the VIA PR if you want to, but I have more fun dreaming up my own stuff!
With that said, what about the Asus A7V266? I can tell you that I think it is simply one of the best mainboards I have ever used. The Asus A7V266 was problem free in every department, and it can certainly be grouped as a "High Performance" mainboard of great quality. I really think there is little you could do to improve upon the A7V266, and it will become a standard here on our testbench.
Memory issues were my biggest concern, but we had no problems with configurations of mixed brand sticks or memory of different sizes. My only regret is that we did not have three 1GB sticks to test the limits.
The layout of the A7V266 is very well designed. It delivers a feature set that is solid, yet transparent. The addition of bumping the stock 100MHz and 133MHz bus speeds is a great marketing tool and conversation piece. I did not think I would be saying this about the A7V266 mainboard, but it has simply delivered stability and performance that many of us have come to expect from Asus while not forgetting about all the bells and whistles that bring so many of us so much enjoyment.
I certainly think that anyone who is an AMD fan would be happy with this board.
