Just as DDR2 went through a maturation process, DDR3 is finally beginning to realize its promise. And with kits from the top contenders already pushing the 2GHz barrier, those looking (and who can afford) to make the jump from DDR2 to DDR3 are taking notice. Up to this point, many scoffed at the idea of spending several hundred dollars upgrading to a DDR3 based system, and for good reason. DDR2 compatible motherboards based on INTEL's P35 or NVIDIA's 680i have, for the most part, served their masters well. Coupled with the retail pricing landslide that's grabbed hold of DDR2 chips in recent months, yesterday's builds have clung to life longer than many in the industry could have predicted, or hoped.
