Budget SLI and Overclocking Motherboard?

[Raginryuu]

Hi All! 

I'm excited to say that I am almost done with my PC build. All that remains is a motherboard. This motherboards does not matter in size (get it?). But I require the motherboard to support SLI for my Gigabyte Windforce GTX 960 4GB, overclocking for my Intel Core i5-4690K, and support DDR3 RAM (4 slots). And of course, I am trying to find the cheapest one out there (that doesn't mean that you get the worst one out there). 

Note:

-I do prefer buying my stuff on amazon

-I'm not afraid of buying used off of amazon as long as it is reliable. 

Thank you all
 

Edit/Change: I have been convinced to change over to the 380 for GPU. There for crossfire needed (not SLI, not sure)?

if you want to see only amazon, go to the link above and click merchants and select amazon on the drop down list

this is the least expensive one on amazon that supports your CPU and SLI and 4 dimm slots
