It's a damn confusing drivers page. You'd think that narrowing down the product that far wouldn't result in so many different drivers.
I'm not sure about the Creative drivers. Might be better to go with Creatives, might be better to go with MSI's version.
The Realtek drivers are probably ethernet, and I'm guessing Windows Update will have a more recent version.
The Intel 3/4/5 drivers are your MoBo's main chipset, you'll probably want these.
The JMicron and Intel RAID drivers are for IDE and SATA. I can only assume that your MoBo has a lot of connectors, and uses both the built-in Intel controller, and extra JMicron controller for even more ports. Normally I'd say that you don't need to install any of this as long as you can get the OS installed, but MSI does say to install one driver (with the red notation) to get better IDE performance.Not that it should matter much, since your HDDs shouldn't be IDE.
The Intel TPM probably isn't necessary if you're not having problems.
