Could you post your motherboard model here.
Something like this will work....http://www.newegg.com/Product/Product.aspx?Item=N82E16813128542&name=Intel-Motherboards
It's kind of difficult to tell on newegg if it supports SLI. There is no way to search for it. This one supports it though, is 1155, and 4 slots. It also has usb 3.0 and Sata3.
Only thing it doesn't have is thunderbolt, if you'd have any use for that.
