ASUS Extreme N5900
 

Overall I like the Extreme N5900, it is a good looking card, plays the
newer games at very respectable rates and falls into a price point a lot
of us can afford. One bright spot is that the ASUS Extreme N5900 is
available now. However, it is a matter of time before we start seeing the
GeForce 6600 series (as well as ATI's X700) come to market, and based on
what we've seen, those cards are going to be a lot faster than the N5900.
