Windows 8 drivers for Dell computers can be downloaded via Dell's standard support site, linked below.
Many Alienware, Inspiron (desktop and laptop), Latitude, Optiplex, Precision, Vostro, and XPS models have Dell-provided Windows 8 drivers.
Dell also keeps a list of their computer systems that they have tested with Windows 8: Dell Computer Support for Windows 8 Upgrade. If your computer isn't listed, it doesn't mean that Windows 8 won't work with Microsoft's included drivers, it just means that Dell does not recommend installing it and will not provide Windows 8 drivers and support.
