I've got a quick question for everyone. I did try to figure this out for myself, but trusted that some of you out there might have some experience with it.

I'm building a computer for my father-in-law and ma switching out a lot of my components and getting new ones for myself.

I've purchased a new E8400, a new 780i (MSI - yes, I plan to SLI in the near future), a new 8800GTS, and even a Tuniq Tower so I can overclock the E8400.

My question is this: (please keep in mind that I want 2x2GB sticks)

What RAM should I get - I'm down to Crucial or Corsair ? (supported by the mobo manufacturer)

PC 6400

CORSAIR XMS2 DHX 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) - 4-4-4-12

Crucial Ballistix 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) - 4-4-4-12

OR

PC 8500

CORSAIR DOMINATOR 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

I was thinking the smart thing to do would be to get the Corsair PC 6400 - especially with the cheap price, but I have had good experience with Crucial. Then I was thinking the Corsair PC 8500 would be great, and it's a decent price and includes the memory cooler.

I was wondering will I ever need the extra speed of the PC 8500, or will the PC 6400 do?

Please let me know what you think.

for me kick the XMS2 to the curb! now it's down to the Ballistix and Dominator.

from there it's a toss up and a matter of $70 bucks possibly!

Ok...just Dominator vs Ballistix.

Now the questing comes down to do I need PC 8500, or will the PC 6400 be enough. Plus the Dominator comes with the Memory Cooling Fan.

Alright...adding another question to the mix.

I was down to the Dominator vs the Ballistix, but now I want to add the OCZ Reaper (PC 8500 - only $110 for 4GB at zipzoomfly.com).

Anyone? Do I go for the 6400, or the 8500. Do I got Dominator or Reaper if I go 8500?

Thanks again.

Will I even notice a difference between DDR2 800 or DDR2 1066? Either way, there are fantastic deals on both sets of 4GB kits.

Any help would be nice.

I'm quite interested in this myself.. I can't decide if I want to go with the 800 or 1066 RAM.

What should one choose if OC the CPU is gunna happen?

and

Whats the difference in performance between the 2?
