Need serious help choosing DDR3 RAM for new build

Guys, i'm getting a new rig and need to pick up some good memory.

Specs are:

CP: Core i7-975 Extreme
MB: ASUS P6T Deluxe V2 (best, because of fitting issues into Antec 1200)
Cooling: Air


Now the RAM questions:

Money not being an issue, Which one of the two woukd you pick:

Mushkin Redline 6GB (3 x 2GB) DDR3 1600 (PC3 12800), 1.65V, 6-7-6-18 - ($199)
CORSAIR DOMINATOR 6GB (3 x 2GB) DDR3 1600 (PC3 12800), 1.65V, 8-8-8-24 - ($170)


Or go balls out and get:

G.SKILL Perfect Storm 6GB (3 x 2GB) DDR3 2000 (PC3 16000), 1.65v, 7-8-7-20 - ($399)
OCZ Blade Series 6GB (3 x 2GB) DDR3 2133 (PC3 17000), 1.65, 8-9-8-24 - ($435)

^^
The main concern here is if these speeds can be achieved on my setup.

Yeah, I do plan to go 6GB only since I don't do any video editiong and the most tasking processes would be the games.

And yeah, money is not an issue at all.

Don't worry about it.... many peeps overclock their i7's to insane speeds on air cooling.....its just a matter of monitoring your temps every now n then....

Btw you won't really need to do much to that 975 since it is stupid fast out of the box...

On a side note :

If money is not an issue get an EVGA Classified motherboard.... as far as x58 goes the Classified is second to none...

But then again if money is not an issue you should not be getting a 1200....

This would be better suited for a Classified and very nice piece of art...

The Thermaltake sword has Massive airflow.... the top panel can fit 4 120mm fans alone...the side can fit 6 120mm and trust me, airflow will not be an issue...

The sword has an astounding number of places for fans(12 120mm), meaning you will actually have a small tornado living in your room......
