Which ram?

[Starpwnage]

I am going to be getting the i5 2400k or i6 2500K (sandy bridge) around the 9th january when it comes out.
However im currently using ddr2 ram, so along with a 1155slot motherboard, i need new ram. I want a minimum of 4gb, and am currently running 32bit, though might to to 64bit soon. Im also looking for 1600mhz+ ram.

I might eventually want to overclock the cpu, though the K edition has unlocked cores, so i wouldn't need to overclock the ram right? Also, i need 2 ram dimm's as each core on intel cpu needs half a channel of ram. However, if windows 32 bit only uses 4gb, it would only be using one stick if i got 2x4gb, so would that mean that the cpu doesnt get the 2 ram dimm's it needs?

Also, does the speed really matter if i wish to overclock with unlocked cores? However, 1600mhz is only a little extra, so i might as well get it.
So here are the choices:

4gb of dual channel memory, 1600mhz and only $60. Not such a well known brand.

Good kit, good brand, 4gb of 1600mhz ram.

http://www.mwave.com.au/sku-37140549-G_Skill_8GB_(2x_4GB)_RipJaws_Dual_Channel_Memory_-_PC3-12800_(1600MHz)_DDR3_-_24
Good kit like above with a good brand, 8gb of 1600mhz ram for use in the future.

Slighlty cheaper then the G-Skill brand, not as well known brand.

4gb of 2000mhz ram. More expensive then the good brand ram, but faster.

First select the motherboard then the RAM.

Have to agree. Easier to answer if you provide a MoBo.

Ill be getting one of the p67 mobos, one of the cheaper ones around 100-150 Australian dollars.

If i got the 2x2gb 1600mhz g.Skill Ripclaws, would they most likely work?
That way i can spend $150 on mobo and $310 on sandy bridge.

Also does 1600mhz make much noticable diffrence in video rendering compared to 1333mhz? I know it will be handy for overclocking with locked cores, though ill get a K edition sandy bridge, so i could save money and just get 1333mhz?

Right now i was thinking of getting http://www.mwave.com.au/sku-37140433-G_Skill_4GB_(2x_2GB)_Dual_Channel_Kit_PC3_12800_(1600MHz)_DDR3_240_pin_DIMM_Unbu

If i get it tommrow while its cheap, i can spend more on sandy bridge.
