I'm in the market for an X800XL graphics card. After looking over the selection at Newegg and other places, I realize I have no idea what exactly I need. So I have two questions: First, can anyone recommend a specific card manufactuer? and Second, if I have a stock Dell 8400 case, in a well ventilated area, will I need to buy an aftermarket cooling fan for the card? I don't intend to overclock it, and I don't usually spend more than two hours at a strech playing graphics intensive games. Any help would be greatly appreciated. Thanks.
