Building a general-purpose rig for gaming, general productivity, and occasional video encoding. I only build a new system every 5 years or so, with some interim upgrades along the way, so longevity is key. I haven't done any OCing yet, but will probably give it a try with the new build. Just want to get the most for my money, and I noticed that some of the DDR3 2000 memory (with slower timings) was priced about the same as DDR3 1600 memory (with faster timings). I realize that faster speed AND low CL is the ideal, but between the two which is better? Or, based on the articles, perhaps I'm splitting hairs?
