So, is SLI worth the cost and the effort? For some, the answer will be a definite no. The SLI boards still cost a great deal, setting up the system is still a daunting task, and the cost of two top-of-the-line video cards will be just too much for many to consider SLI to be a real option. However, we are confident that SLI and nForce4 work as they should and we have managed to finally achieve a stable SLI system with each of these four motherboards. In the end, nothing else will provide the gaming performance that a tweaked and stable SLI system can deliver. If the best performance possible is important to you, then the answer to whether SLI is for you will likely be "yes". [URL]http://www.anandtech.com/mb/showdoc.aspx?i=2358[/URL] Ed
