If you plan to have the best framerates, don't go with a cheap mobo. Buy yourself a great mobo to fit with great graphic horsepower.
That board supports both Crossfire and SLI as every top of the line technologies:http://www.newegg.com/Product/Product.aspx?Item=N82E16813130597
Wanna buy a budget 100-150$ board?? Then buy only one graphic card.
You look like you'd get a formula one engine and fit it in a civic berline... sorry but you have to buy both in the same category. It would cost more money (and time) just to configure the formula one engine to be compatible with the car's body, and it won't ever match that full-feature formula one... neither a porche or ferrari... it will still look like an ugly civic.
Furthermore socket 1155 will be compatible with the next Intel cpus so better get the best so that your chances of getting these new techs on it are higher.
