Help me pick some RAM please!

[Slipperss]

I need some good ram and i really got no idea of what to pick.

My current built is like so:

Mobo - ASUS P6X58D Premium(not clear)

PSU - Corsair 1000w

Cooler - Water

RAM - *Missing* (Looking for some which would be best for my system)

Case - Corsair 800D

CPU - Intel Core I7-930

HDD - WD Caviar Black WD1001FALS

GPU - 2x 5970

I thought about some Corsair Dominator's

I heard these should be really good (Also really expensive)
CMGTX2

These timings are really fast.. But it does also say "Ultra-low latency 4GB DOMINATOR GT kit optimized for Phenom-based DDR3 systems. 1600MHz, 6-6-6-18, 1.65V"

I could use some help picking the best ram for my system. (Cheapest and Best(more expensive)

Also, i see alot of gamers with the P6T7 WS supercomputer mobo. Why is that?

Could also need some help picking a gamer mobo (Cheapest and Best(more expensive)

As far as RAM goes, I think you'll find the following three articles helpful:
Core i7 Memory Scaling: From DDR3-800 to DDR3-1600
DDR3 On A Budget: Six 6 GB Memory Kits
Memory Scaling on Core i7 - Is DDR3-1066 Really the Best Choice?

Suggest you avoid Dominators, Ripjaws and other modules w/ tall heat sinks if you are going to Overclock.

DDR3-1600 is overclocker's choice .... assuming not using LN2. AFter that its lowest CAS # you can afford. CAS 6 costs more and is faster than CAS7 and so on.

CAS 6 Mushkin Redlines are low profile w/ 6-8-6-24 timings and go for about $250

CAS 7 CORSAIR Model CMX6GX3M3C1600C7 are low profile and go for bout $200

CAS 8 OCZ Gold Model OCZ3G1600LV6GK are low profile and go for about $158

CAS 9 is more expensive than CAS 8 of late so why bother

These selections are based upon what's on the labe;l....often times modules perform better than their label and to save some $$ you might wanna scour the THG sample builds to see what they have ID'd.

The supercomputer can do triple SLI / Xfire + PhysX (4 cards) so that's why it's popular w/ extreme gamers. The soon to be top dog is the Rampage III Extreme....release any day now I expect.

Hai again, just wanted to know if anyone knows what the FPS difference would be in games with these different rams.

TR3X6G1600C7D 7-7-7-20
Vs.
CMT4GX3M2A1600C6 6-6-6-20

The GT kit is only 4GB.

Did you read the reviews I linked? In many cases, the difference in average frame rates with 6GB of memory between 1600 C7 and 1600 C6 was 0.2 frames.
