DDR2 provides the best value for the buck. Having said that... if you are installing a high end CPU, DDR3 is best for you!

This.

There are better DDR3 kits out there. Honestly, you wouldn't be able to tell the difference between the two regardless of your task, especially with that CPU.

i'd also go with the DDR2, having your RAM frequency much higher than your FSB (i.e. DDR3 1600) wont show much of a boost, especially with a C2Q.

The story is...
Something is wrong with my GA-X38-DS4 mobo and is give me BSOD when i insert ram with 1066mhz,so for the moment i will use ram with 800mhz until i find the solution.
And i must choose the best for me from my box (i have 5-6 different dimms)
The best are...

B) GEIL GB22GB6400C4DC DDR2 2GB (2X1GB) BLACK DRAGON PC6400 800MHZ DUAL CHANNEL KIT 4-4-4-12 (2GB)
OR
Kingston ValueRAM (2X2GB)4GB DDR2 800MHz PC2-6400 System Memory, 240-pin DIMM, CL5, Non-ECC, Unbuffered, Model: KVR800D2N5/2G 5-5-5-18 (4GB)

I use my PC for high end gaming so...which is better for me to use?

the type of RAM you run is nowhere near as important as the amount of RAM you have, especially with these new MS operating systems....

i.e.

you'll probably find 3gb DDR2 667mhz will run faster than 2gb DDR2 800mhz, you really want 4gb for intensive gaming, my rig constantly passes the 3gb mark even while running pretty mediocre games...

i'd rather run my DIMMs in single channel & have more of it than trying to keep the sticks matched for dual channel & actually using less.....

What about those?...
Kingston ValueRAM (2X2GB)4GB DDR2 800MHz PC2-6400 System Memory, 240-pin DIMM, CL5, Non-ECC, Unbuffered, Model: KVR800D2N5/2G 5-5-5-18 (4GB)

they'll be fine......, they wont clock very well past stock, but they'll serve you well for gaming.
