What is MT/s and how do I match it to my CPU?

I'm building a system using

AMD Athlon II X3 455 Triple Core Processor - $80

and need to find a motherboard for it. Someone mentioned to me I need to get a 5200 MT/s and not 2000 MT/s. What does this mean, and how do I find out what MT/s works with what CPU? I looked at the AMD site for mine and wasn't able to find this.

    This is a detail you do not need to pay attention to. Just get a board with an AM3+ socket, and all will be good in this regard.

    Here is an excellent and very popular MB in the 100 price range:

    GIGABYTE GA-970A-UD3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

    See this article at Hardware Secrets for a concise explanation of these transfer rates and why you need an AM3+ socket MB to get the highest rate.

  2. From this part:

    1,800 MHz = 3,600 MT/s = 7,200 MB/s
    2,000 MHz = 4,000 MT/s = 8,000 MB/s
    2,400 MHz = 4,800 MT/s = 9,600 MB/s
    2,600 MHz = 5,200 MT/s = 10,400 MB/s
    Socket AM2+ and AM3 processors and their companion chipsets, however, are limited to the 8,000 MB/s transfer rate. Only socket AM3+ CPUs and chipsets are capable of using all the speeds published above.

    Does this mean that since the CPU I'm using is an AM3 socket, it doesn't matter if I get a 4000 MT/s, 4800 MT/s, or 5200 MT/s mother board?

    Also, if I don't plan on upgrading my system with the future, is it okay to just get AM3 motherboard for my AM3 processor?

    That's theoretically true. However, you'll be hard pressed to find any AM3 MB's with all the modern connectivity that you'll probably want.

    Also, if I don't plan on upgrading my system with the future, is it okay to just get AM3 motherboard for my AM3 processor?

    Yes, it's OK, but it's shortsighted. You're better off spending a few dollars more for an AM3+ MB now, and at least have the option to upgrade your CPU later than be absolutely locked into an old CPU.
