I need a motherboard and processor to start this build. Has to be SLI capable (will be running 2 XFX 8600GT cards). Been planning on going with the Core 2 duo but I'm not set on anything yet. Going to be used primarily for development, but some of the programs tend to be resource demanding (CS3, eclipse, etc). Not looking to spend a fortune on it. And while you're at it, thoughts on this case? http://www.newegg.com/product/product.aspx?item=N82E16811119142 (I'm a fan of the top mounted ports) 550W should be enough to power everything shouldn't it?
