G.Skill's Trident series isn't a new series to us and is something we've looked at a couple of times already. The first kit we looked at was a PC3-19200 8GB kit that did a good job of impressing us with its default 2400MHz DDR clock and price tag that came in at under $100.
The other kit we looked at also did a good job of impressing us, but due to its higher speed, it carried with it a higher price tag, and slightly more relaxed timings. The PC3-21300 8GB kit ultimately performed very well and was a good option for people wanting a higher speed kit.
