    I need to get a Boot hard drive for my computer. I want a hard drive and not an SSD.

    It looks like I can get a WD Raptor with 10,000 RPM speed, but SATA II

    or

    I can get a 7200 RPM drive with SATA III.

    My motherboard has SATA III.

    Question: Which would be faster for booting and applications (not going to store data on it)?

    10k @ Sata II

    or

    7.2k @ Sata III

    I would go for the SATA III drive as it's theoretically twice as fast for transfer speed compared to SATA II. That will (potentially) lead to much better performance than the 10,000 rpm will give you over 7,200 rpm.

    Mechanical drives cannot sustain read and write speeds beyond what SATA II can offer just yet, they only benefit from having faster burst speeds. Hard drives are limited by the internal moving parts, so a faster spindle speed is beneficial.

    Are you also opposed to a hybrid drive such as a Seagate Momentus XT Hybrid? It's a mechanical drive with a small SSD, best of both worlds.

    The current Western Digital VelociRaptors(10,000RPM) are the fastest mechanical drives available, and the latest versions have bigger caches and they even have a SATA III interface for those ultra fast burst speeds.

    Older SATA II Raptors and VelociRaptors are not really worth considering anymore, the newest 7200RPM drives can keep up or outperform them now, not because of the SATA III interface but for the same reasons the new Raptors are faster than the old Raptors; newer technology and faster processors on the drives.

    If those are still too pricey than higher end drives such as the WDC Black Edition drives are also quite fast, and pretty much any modern drive will be faster then an older drive due to advancements.
