DDR2 still hasn't died off, and even Intel is still a supporter of it. DDR3 may be the future, but the present still belongs to DDR2. AMD is still dependant on it for its AM2 and AM2+ processors as well. Intel P45 chipsets still have a DDR2 memory controller integrated and with the price of DDR2 vs. DDR3, it's still wiser to go for DDR2.
Chaintech APOGEE memory isn't anything spectacular compared to other brands, however it's not far behind the big names like Geil and Aeneon. So when it comes to choosing what you're going to buy, Chaintech is something we would recommend to anyone looking for high performance DDR2 memory. The only downside is that here in Australia it may be quite difficult to locate, though you won't find too much of a problem getting it in the states.
