Just remember that if you go with a Via solution that you can't get the native resolution for most 7" monitors out of the onboard video. And you will probably come to find out, as I did, that the onboard audio won't cut it! After I bought the Via MII 10000 I discovered this, solution being to run powerstrip and buy an Audigy 2 NX. And this was after lurking for about 4 months on the boards.
Great questions and do your research before you buy!
