My more finding suggests that Kingston performs well on Asus boards. Corsair and OCZ are known as the gaming brands while a pair of Kington 1gb performance dimms serves well for that nigtly stretch of gaming and game modding. For the basics and still getting a bang for the bucks on a dual core cpu AMD's 3800+ X2 works as the starter. The link here will provide some recommendations for different builds depending on what type of case you are going to put together.
