"Despite the fact that DDR3 has a slightly better performance and consumes less power compared to DDR2, it is still hard to recommend DDR3 unless you have a huge chunk of money to spend. For a far less price, one can purchase 4GB (2x2GB) DDR2 instead of the more expensive 2GB (1X1GB) of DDR3. Not only is DDR3 so much more expensive compared to DDR2, in real-world, you would hardly see a major performance increase using DDR3. Of course, this could all change in the very near future as DDR3's price will drop with more motherboards on the pipeline supporting it and manufacturers ramping up the production. Until then, DDR2 is still a better choice to buy. That is why we are seeing many memory manufacturers still not giving up the DDR2 and releasing higher performance DDR2. A month or two ago, OCZ the released DDR2 PC2-8500 Reaper HPC 4GB Edition. This is one of the highest clock speed 4GB DDR2 that is available on the market. Today, join us as we put this memory to the test."
