As for memory, I am looking at the G.Skill Trident or Ripjaw lines. My motherboard is rated to run DDR3 1600 RAM naively but can take RAM that is overclocked. Seeing as I have never done overclocking on RAM before (but I would like to), which clock speed for RAM is good to get? Should I go with the DDR3 1600 RAM with the tighter timings or the RAM that is rated at lets say 2133 with timings that are not as good as the 1600 RAM?
Any advice you could offer would be appreciated. I would like to keep the cost for RAM around <$135.
For what you are looking for I would suggest a 1600 or 1866 RAM kit. There are a couple reasons.
1. OC'd RAM is not noticeable in performance, and only gives a less than 5% increase in synthetic benchmarks.
2. Although the higher speed kits are designed to have headroom to work up to that speed, you will have to OC both your CPU and RAM to get it to that speed in most cases.
Basically, unless you are attempting to beat world records, and are experienced in OCing I would stick with a tighter 1600 or 1866 kit, spend the extra money to bump yourself to a 16GB kit, or use the extra money elsewhere.
As far as the brand goes, G-Skill is very solid, as are Corsair and Kingston.
