I have an i7 950 chip and matching gigabyte motherboard which has six memory slots. I am going to order corsair triple channel 2000 mz. ddr3 (12 gig). does it make sense to go ahead and buy a second set to fill all six slots and have 24 gig of memory. But I heard that the memory speed then drops. I am a novice and any insight is helpful. I am a gamer for games like stars wars mmo and eve.
