If you're on something like Win 7 and you've been toying with the idea of trying Linux, give Mint 15 with KDE a whirl. I adapted to it fairly quickly. I've been experimenting with it off of a bootable usb drive. I used the Universal-USB-Installer-126.96.36.199 to create it. It's solid for general use and multimedia. I've not had issues yet. Processor and GPU = FX 6300 @ 4.66GHz and GTX 660.
