Kingston ValueRam DDR2 2GB PC5300 CL5(KVR667D2N5/2G)
Kingston ValueRam DDR2 2GB PC6400 CL6 (KVR800D2N6/2G)
Also, I what is the difference between DDR, SDRAM, SO-DIMM, SO-DDR, DDR2 and DDR3? Which should I use?

I might need a new motherboard or CPU, so I'd need a new set of RAM as well that would fit in. I'm not sure yet if they need to be replaced.

Is DDR3 much better than DDR2 or is there little difference in performance?
