Things are about to change in desktop memory. DDR3, which has been getting a bad rap from Intel users, is about to bloom into its heyday. DDR3 memory will run on pre-Nehalem series CPU's, but it was really designed with Intel's Nehalem in mind. People who scoffed at DDR3 as not being much better than DDR2 will soon have their noses rubbed in it in a big way.
The limitation with DDR3 hasn't been in the design of DDR3, which in itself is an elegant design that was well planned and well executed, but the bump in the road with DDR3 has always been with the motherboard and CPU limitations placed on it.
OCZ was nice enough to ship us a two Gigabit kit of their OCZ PC3-16000 NVIDIA SLI-Ready Edition DDR3. Scoff if you will, but you need to take heed from those that have had Nehalem in hand. DDR3 is coming of age and it's good. It's really good. It's really fast. And it will be one of the most sought after performance products as soon as the Nehalem flood gates open.
