Hey joni944,
deffo pick up one of the new Radeon HD4670 cards, as mentioned they are the bees knees for Full HD viewing, they have a number of video enhancements over the older HD38xx series including the ability to upscale DVD to HD which sounds neat!
And not that it's a priority for you but should you fancy some gaming the HD4670 is suprisingly good at rendering games in HD resolution (1280x720)
This card is an absolute bargain!
