Asus Z97-A or Asrock Z97 Extreme 4 will do at less cost .

For me , i7 4790K will work at x8/x8 at SLI/Crossfire

If you just want to SLI and overclocking.
I would go this.More cheaper......

Motherboard: MSI Z97-G45 Gaming ATX LGA1150 Motherboard ($121.99 @ Newegg)
Total: $121.99

This board suport 3-way SLI(Gen3 (16,0,0), (8,8,0), (8,4,4)),if you want to 4-way SLI you should go Gigabyte GA-Z97X-Gaming G1 WIFI-BK or ohter high-end motherboard.But....that board always too expensive.
