G'day I am wondering what mobo I should go with for my new build:

CPU: Intel Core i7 2600k (OC ~4.7GHz planned)
COOLER: Noctua D-14 or Coolermaster V8 (looks better)
RAM: 16GB (4x4GM) G.Skill Ripjaws X 1600
GPU: Powercolor 4GB 6990 OC (CF in future / possibly CF 2 * 6970s instead)
PSU: Corsair AX1200 Gold
SSD: 120GB OCZ Vertex 3
HDD: WD Caviar Black 2TB
DVD/CD: Samsung SH-B123A Blu-ray DVD combo
- 2 additional Coolermaster red LED 200mm mega flow fans possibly another smaller fan
- Lamptron FC5 V2 Controller (dont like running that many fans off mobo)

Budget: $3,000 AUS
Resolution: 3*24" eyefinity (6024*1080)
Usage: Gaming, Graphic Design (photoshop illustrator), 3D Modelling, very small amount of video editing

Mobo: considering ASRock Z68 Extreme 4

Is something like the ASUS Maximus Extreme IV Z worth the extra cost?
or ASUS P8Z78-V Pro?
or Gigabyte UD7?
or other suggestion?

(6Gbps SATA and USB 3.0 are wanted (2*USB 3.0 fine))

Thanks in advance for any advice.
