Need some good ddr2 800 cheap

[snake_pliskin]

I want ram to be able to overclock my E6300 and be good for gaming and defently want it to be 800. This is what I have looked at so far Im putting it in a P965 board. Also if I buy these 2x512 packages and later I throw in a 1GB chip will that conflict with the dual channel of the other 2 chips or any other type of conflict?

OCZ "not very good reviews for the P965 board"

Any other suggestions? Im kinda poor right now
