    I got my system over weekend with following config
    P8600
    2GB DDR2
    160GB
    FullHD
    Vista 64bit premium
    I'm planning to upgrade RAM and I'm thinking if it is worth upgrading to DDR3 instead of DDR2 4GB. Price difference between two seems to be like $20-$30.

    A system which uses DDR2 modules cannot fit DDR3.

    if it already has ddr2 then ddr3 will not work. ddr2 slots have 200 pins and ddr3 slots have 204. so ddr3 will not physically work. oh well, as of right now ddr2 800 is faster than ddr3 b/c of cache latencies.

    if your notebook came wid DDR2 then you can't use DDR3.
    you can't feel speed.

    The theoretical improvements in speed are quite negligible, as are the improvements in power efficiency. But in either case, you cannot upgrade to DDR3, as the other posters have said - so don't worry about it ;)

    There are also many benchmarks out there that show no real noticeable gain from switching at the moment.
