[New System] Advice is all I'm looking for

Been reading a ton in here, and gaining a lot of sweet info  
So to top it all off i figured i would do a nice post here and hopefully gather a bit more information..!

Approximate Purchase Date: Within the next few days

Budget Range: pricing should be around the parts I already gathered (Stuff in DK is more expensive then US, so giving a number here would be wrong)

System Usage from Most to Least Important: Gaming 90% of the time  

Parts Not Required: Got everything else needed.

Preferred Website(s) for Parts: Danish page , proshop.dk , but feel free to give links to newegg or w/e.

Country: DK

Parts Preferences: Don’t care, as long as it works im cool  

Overclocking: Yes

SLI or Crossfire: no

Monitor Resolution: 1920x1200

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000

SAMSUNG 830 Series MZ-7PC128D/AM 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD) Desktop Upgrade Kit

Noctua NH-D14

ASRock Z77 Extreme6 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)


Found the following parts, although I really don’t know if it’s the right motherboard for me. Considering I don’t plan to have SLI at all. I've been looking a bit at the extreme4 motherboard to save a few bucks. But any other suggestions is always welcome.
The last build i had, i did not OC much, although my plan is to do it with this one  

Any advice would be appreciated.
Thanks in advance.
(If there is some typo's , deal with it !)
