Nvidia 'fessed up by reporting its revenues for 2Q/08 would not meet previous forecasts. It is taking a $200M charge and reducing its revenue to $875-950M (from $1.1B).
As recently as last week, I found out that AMD-ATi was releasing an HD4870 and HD4850 graphics card at prices ($299US, $199US respectively) that would not only compete against Nvidia's mainstream 8800GT/9600GT/8800GTS cards, but also against its high-end GTX 260 and GTX 280 cards (priced at $380Cdn and $660 Cdn, respectively). With AMD stock trading for $5 and change, it might be worthwhile to consider taking a position on this underdog.
