    DDR3 worth it?

    My mate is going to build a new PC soon but we don't know if it should be with DDR3 or DDR2. I know it is dependant on what Mobo etc. Would there be any noticeable benefits in going the DDR3 route?

    Re: DDR3 worth it?

    Good question, DDR3 has greater latency than DDR2 however it has much higher bandwidth. So single random addresses in memory will be a bit slower however if you want a large data block that will be faster. As systems are requiring more and more memory, something that can throw chunks of it around faster is better in my book.

    Re: DDR3 worth it?

    What path is he going down becuase the Intel Core i7 only supports DDR3. Where as the AMD AM2/AM3 support DDR2/3 (DDR3 for AM3 only) as well as the Core 2 chips which support both DDR2/3

    Future pricing.
    DDR2 will only get more expensive now the balance has shifted towards DDR3.

    Re: DDR3 worth it?

    DDR3 prices are close to DDR2 these days, and you would also have the advantage of reusing the DDR3 sticks for your next motherboard upgrade.

    +1

    In the future you might want to upgrade that box to 16GB as a mid-life tweak from the 4GB/8GB you build it with now. Will be nice to have the option.

    I'm sure I saw some benchies recently that gave a slight nod to DDR3 for performance as well, which makes sense as the technology has had time to mature.

    +2, especially if starting from scratch. I would also advise against looking at 775 as its more or less obsolete now so building a new system based on it is pretty pointless, imho.
    Hack: i5 2500~ASROCK Z68 EXTREME4 GEN3~8GB Vengance~HD4770~ ANTEC 302~CX600.
    Gamer: i7 3820 @ 4.4Ghz~MSI X79A-GD65~16GB Redline 2133~Gigabyte GTX580~TT A90~CM SILENT PRO 1000w.

    Re: DDR3 worth it?

    Depends on requirements and budget.
    As has been said different motherboards/cpu's are limited depending on which you get.
    DDR2 can be got pritty cheap now, although DDR3 has come down alot and esp for larger amounts of memory it's a better option.

    For socket 775 you can get ddr3 motherboards but there's no real improvement with ddr3
    For socket AM3 you're looking at DDR3 and it's a reasonable improvement over AM2+ with DDR2
    For socket 1366 and i7 cpu it's ddr3 only


    EDIT: One thing to note, socket 1366 and i7 cpu uses tripple channel, so you want to buy sets of 3 or 6 sticks, AM3 & CPU use double channel so you want to buy sets of 2 or 4 sticks
