AMD announced the mid-range (and perfect for HTPC use) 4600 series cards today. Below are pertinant excerpts from their PR: 

The ATI Radeon HD 4670 and ATI Radeon HD 4650 graphics cards feature AMD’s TeraScale graphics engine, with 320 stream processing cores, and are based on AMD’s advanced second generation 55nm process. The result is that even in today’s most demanding games like Crysis, the ATI Radeon HD 4600 series delivers up to double the performance of competing products at the same price. Both the ATI Radeon HD 4670 and ATI Radeon HD 4650 deliver substantial gaming horsepower with minimal power draw – the ATI Radeon HD 4670 operating at under 60 watts and the ATI Radeon HD 4650 operating under 50 watts under full load – eliminating the need for additional power connectors and making installation a cinch. The ATI Radeon HD 4670 is immediately available with a frame buffer of 512MB GDDR3 memory with an MSRP from USD $79, while a 1GB DDR3-based variant is scheduled to ship later this month. The ATI Radeon HD 4650 features a frame buffer of 512MB GDDR2 memory and is expected to be available later in the month at an MSRP from USD $69.

Stunning HD viewing experience
The ATI Radeon HD 4600 series brings high-definition, home theatre quality video features to the mainstream segment. AMD has incorporated its second generation Unified Video Decoder (UVD 2.0) for advanced hardware HD video processing ensuring a smooth HD viewing experience on HD-capable monitors. In addition, it features support for HDMI 7.1 surround sound audio for an immersive big-screen entertainment feel.

Home theater enthusiasts will be captivated by ATI Avivo HD technology that delivers sharp images and vibrant color fidelity for Blu-ray and HD content. In addition, ATI Avivo HD technology delivers dynamic contrast adjustment for a crisp, vibrant picture with incredible quality, the ability for users to upscale DVD content to nearly twice the display resolution of HD content, as well as take full advantage of Blu-ray functionality with picture-in-picture capabilities for bonus features such as director commentary.

Unsurpassed performance-per-watt
Built with efficiency, scalability and performance in mind, the ATI Radeon HD 4600 series sets a new performance-per-watt standard for mainstream graphics products, thanks to the enhanced bandwidth of DDR3, new power management capabilities that provide greater performance and efficiency, and 55nm technology. The series features AMD’s second generation ATI PowerPlay technology which allows for automatic power adjustments based on the activity of the graphics processing unit (GPU), resulting in significant power savings when the GPU is idle. Moreover, ATI PowerPlay enables advanced clock gating, as well as increased voltage and memory scaling, delivering performance on demand with exceptional efficiency.
