I have about a £900 budget, but I am a bit lost when it comes to motherboards. I am leaning towards a GA-Z77X-UD3H or just a GA-Z77X-D3H and save some money, since they sound very similar from what I see. Anything under budget, I am going to spend on peripherals (mainly keyboard). 

I want to get my feet wet with overclocking and all that fun stuff

I have a Phantom 410 and an Evo 212 I already own that I am using, along with a HDD and OS so I left that out of the parts list above.

Any help with the Motherboard choices (does not need to be any of the ones I listed), or on my build choices overall would be greatly appreciated. 


The ASRock Z77 Extreme4 is widely recommended as a "budget" overclocking motherboard. http://www.overclockers.co.uk/showproduct.php?prodid=MB-064-AK&groupid=701&catid=5&subcat=2261

Provides 8 phases to the CPU for increased stability and has everything else you need on a motherboard for a sensible price.
