I guess it really depends on what your going to be doing with your computer.
Also, just how far you want to be able to upgrade it in the future.
For example, we know for a fact that nForce2 will support Barton, so it is a sure upgrade route. With KT400A coming out sometime next year, I really can't see KT400 or KT333 boards being very attractive. I don't know if KT333 supports Barton, but I'm almost sure KT400 is supposed to. Somehow (Disclosure: I
am biased against VIA), I don't get a warm fuzzy feeling when VIA goes KT333 then KT400 then KT400A, all with little performance increase. It just doesn't sit will with me.
As for picking an nForce2 motherboard over an nForce1, it was so you could have a sure upgrade path later on. The only reason to buy an nForce1 today is either you are really price constrained, or you
need the integrated video the nForce1 boards offer (until IGP nForce2 hits the streets).
Another reason for picking the nForce2 board is that it has built as good as current add-in sound cards. We can all split hairs, but they are all close enough for what most of us do that they are equal except in terms of price, and that is built into the price of the mainboard. For $150 USD, the Asus nForce2 is a pretty good deal for a builder who doesn't have a good soundcard laying around. Find a soundcard as good as the one built into the nForce2 and add that price onto whatever KT333/KT400 board you're looking to get and I'll bet your at or over $150.
I'm really not up to par on video cards, so I didn't make a recomendation on one. As for Kingston RAM, I'll just say that I've less than stellar experiences with it. For me, Corsair, Crucial, or Mushkin are the only trusted options; with Corsair and Mushkin being the more high end stuff.
The front page is most likely out of date (as happens in our hobby), so it most likely isn't a good reference point.
Hope some of this helps!
