Which passive sinks are useful and which are useless?

I've got a bunch of BGA RAMsinks coming soon. I've also got a few TSOP RAM heatsinks sitting around. I'm wondering what winds up being useful, and what is counterproductive.

I'm assuming that the BGA RAMsinks on the MOSFETS is useful, because MOSFETS put out so much heat. I know my Southbridge heatsinks will be useful on the MCP-T Southbridge. I'm not sure about the BGA RAMsinks on a Radeon 9800 Pro's BGA RAM, or about the TSOP RAMsinks on the TSOP RAM of a 9600 non-pro... opinions?

    AFAIK the ram sinks are pretty much useless. I saw a thermal image of a nF2 board and the southbridge and mosfets are one of the hottest spots on the board so I guess heatsinks there would help.

    <b>General heatsink overview:</b>

    CPU? Duh.
    GPU? Duh.
    MOSFETs? Check. Does it hurt to touch it? A heatsink might do it some good.
    Voltage regulators? Check. Does it hurt to touch it? A heatsink might do it some good.
    DIMMs? No. Not even.
    Video RAM? Possibly. Vague and subjective increments.
    MCP-T? Yeah. Heatsinks make it happy.
