New Pc Ram decision HELP

[Metal_maniac1]

Hello,
just bought most of my new system
Thermaltake Pro Water 850i Liquid Cooling Kit
Seagate SATAII NCQ 1.5TB 7200RPM
OCZ 60G Vertex II E Series SSD
Intel Core i7 930
Gigabyte GTX465 1G
Gigabyte GA-X58A-UD5 MB
CoolerMaster 850W Silent Pro modular PSU

Looking at getting ram, toss up atm between
Corsair DOMINATOR-GT 3x2GB PC16000 2000MHz (CMT6GX3M3A2000C8)
- $337
and
Gskill PI series 3x2Gb PC16000 2ghz (B/D-TR-F3-16000CL6T-6GBPID)
- $316
Gskill is CL6 and Corsair is CL8
I know lower lat is better but why are dominators so expensive? and why is this dominator so much cheaper then (CMG6GX3M3A2000C8) i know theres a slight diff in latency (8-9-8 vs 8-8-8) but its like a $200 difference in price

Recommendations for my new PC, between the 2? other recommendations? (prices in AUD btw)

Also (im kinda a newby at understanding how much depth there is in ram @_@) "faster than PC3-12800/DDR3-1600 are not JEDEC standard modules, they are simply modules with higher tolerance chips or are over-volted."
Does this mean both of these modules need to run at 1.65V to hit 2ghz? Will this effect longevity?

Hello and welcome to the forums
Well Corsair dominator series has always been more expensive(compared to other Corsair models)because of having a better cooling and usually better OC'ng potential.
However even for a good OC,i would recommend going with a DDR3 1600 RAM(CL 7/8),because it will be fine and costs less than DDR3 2000

Hi newcomer and welcome to the Tom's hardware forum.

I agree with Maziar, the G.Skill are much better for price/performance that the Corsair.

U won't see any difference between 1600 or 2000 since the timings are different in both and better in the G.Skill RAM.
