http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006 Will this be good enough for sli? because I already bought it and it said it was sli ready so I figured it would work then I did a little more research and found out that most people recommend 850. And I'd hate to have wasted all that money.. I also have a 4670k, 8 gb of g.skill ripjaws. a cooler master 212 evo cpu fan a z87 l337 gank mobo, and a cheap 1tb western digital harddrive.
