Low latency or high clock speed for workstation?

[saudade]

Is low latency or high clock speed preferable for a work station build? Will be used for lots of multitasking (mostly graphic and 3d programmes as I am an architecture student - e.g editing large Photoshop files whilst rendering in 3D Studio Max)

I am looking at:
G-Skill RipjawsX 8GB DDR3 2133MHz CL11 (11-11-11-30) 1.5V
vs
G-Skill RipjawsX 8GB DDR3 1600MHz CL8 (8-8-8-24) 1.5V

both seem around £60-70 mark and I was wondering what performance differences are likely to be? Here's the rest of the build:

Intel i7 2600k
Asus P8Z68-V PRO Z68
PowerColor HD 6850 SCS3 Silent 1GB GDDR5
Corsair 120GB SSD
WD 1TB Caviar Green HDD
Antec CP-850 PSU

Any advice would be great, this is my first build.

Raw clock speed always wins out over latency differences. At least that is the conventional wisdom.

Ok thanks. Also I read a few articles that say it's not worth buying more than 1600MHz for sandy bridge processors as gains are pretty minimal - Is this just the case for gaming? I was wondering if there'd be a bigger performance increase with doing heavy graphics work
