Radeon HD 4890 Driver Incompatibility With Windows 8?

Hello everyone. I've recently installed Windows 8 x64 on to my desktop that was formerly running Windows 7 x64. On Windows 7, display drivers would be defaulted to the generic 'plug and play' driver upon fresh installation of the OS (on Windows 8, it is called "Microsoft Basic Display Adapter"). I could then locate the proper drivers on the AMD site or I could use the "auto-detection" tool (http://support.amd.com/us/gpudownload/windows/Pages/auto_detect.aspx) to detect the proper driver to install.

Here's where the problem comes in: when I perform a fresh install of Windows 8, the system now detects that I'm running an AMD Radeon HD 4890 and opts to install a driver called "ATI Radeon HD 4800 Series (Microsoft Corporation - WDDM v1.1)." It doesn't even do this through Windows Update. Yet now, the fans in my system seem to be blowing slightly louder, the auto-detection tool can't properly detect what video card I have (as opposed to when it did on Windows 7), and I'm unable to determine if the Catalyst drivers are supposed to be better than the ones supplied by Microsoft. I tried installing the Catalyst drivers from AMD's website, but now odd things are happening on my OS (ie: the titles of services in System Configuration aka 'msconfig' has been abbreviated and seem broken, and there's two identical keyboard devices listed in Devices and Printers when I'm only using one). I don't know how a video driver could 'break' things as it's done, but I am quite positive that this was not occurring before I downloaded the AMD driver.

Could someone help clarify this as I'm quite confused as to which drivers I should be using (AMD vs Microsoft), I'm not understanding why the auto-detection tool isn't detecting my video card properly, and I have no idea why the titles of certain things (ie: msconfig) are jumbled now. Thanks.

AMD drivers should be best for the system and performance. I remember seeing on their website that the drivers didn't fully support windows 8 features but 12.6 legacy is compatible with windows 8.
