In that case i'd wait for the G1 Sniper 3 or Maximus V Extreme to be released.
It's a unusual suggestion but you might want to have a look at the asus P8Z77 WS
Would have to say the p8z77 deluxe or wait for the full rog board. the reason I would go Asus over others(besides really liking Asus in general) is the memory traces use a next gen standard allowing for higher mem ocing. watch the video on newegg jj explains it all pretty well. the software included with the Asus make fan controls and in windows ocing very easy and works well. I think you will find every option you would need for ocing your ivy to the max without going for a ln ocing record. just an fyi about fan controles. to control the cpu fan headers you need 4 pin pwm fans or it defaults to full speed. all other fans can be controlled though voltage or pwm(3 pin or 4 pin)

Z77 Deluxe is overpriced. The MSI GD65 is just as good at overclocking and has almost all the features the deluxe has for £50 less. Plus all the new Z77 boards can take memory at much higher clocks, it's the new memory controller in the Ivy Bridge chips, it's not just Asus boards
yes the memory controller is key but given the choice I personally prefer the better memory traces and more so the extra software. for me it was worth the extra price. not to mention the built in wifi/ap/packet control. the fan xpert and windows ocing software is also top notch. At the end of the day im sure the oc will end up the same on either so it really all comes down to what software/hardware features you prefer vs price.
edit btw asus claims to hit 2400 ddr3 speeds on all the p8z77 boards and 3400 on rog in the lab with ivy. lol I don't suppose it means much in extra performance but its there if you want it.
