I totally disagree with your assesment of Via and Asus.
In the past Via did have some issues with thier past chipsets, but their new k8 series have been perfoming well. True that they don't support Raid0+1, but then again as a home user who is on a budget can run the raid 0 and still back it up with just a purchase of external HD rather then shell out for one more SATA HD. I bring that point up because in some reviews like the XBIT review of the new Asus AV8-E Deluxe MB which uses the VIA K8T890 chipset, they knock it for those reasons. I really don't have the money to be buying 4hdS, so people like me are satisfied with the features they offer. True the NF4 ultra chipsets do perform a little faster, not much I may add, unless you sit there and run all kinds of benchmarks, but again people like me are pretty much satisfied with the perfomance.
Now about Asus, Never had any problems with any of thier products. They have been around for awhile, and continue to manufacture good products. I purchased a new 939 socket mb myself, A8V-E Deluxe and must say I am a satisfied costumer.
No problems as of yet. Thier SLI boards I hear are pretty good too.
I had to get that off my chest, I understand people like to OC and bend and benchmark thier systems to get that little extra out of the system. I do too, to some extant. But people slam other products for some silly reasons. If a product performs well and is reasonably priced, and has alot of features, why knock it?
