The Asus HD4670 is an excellent video card - it's cheap, uses little power, and can run most (if not all) new games at mid-high settings on lower resolutions. I bought it as an upgrade from my old Nvdia 7600, and I have not been disappointed: its incredibly low power consumption (requires no extra power lead) was a massive drawing point to me, as I have a tired, old PSU so any other graphics card would require that to be updated too. However, with only 512mb of DDR3, it does have issues with higher resolutions and shouldn't be considered on a serious gaming rig, espically with its very medicore clock speed of 750 mhz. That said, for home theater use, it's very difficult to beat it for its price. In fact, it almost seems this card was made for home theater PCs - it has a low power consumption, a fairly quiet fan, and full HD output (including sound via HDMI cable). It would also be a great card for someone wanting to do some low-end gaming on a budget, or who uses 2D image editing software (ie Adobe Photoshop) often.
The ASUS EAH4670 series utilizes a specially designed fansink that effectively dissipates heat away from the graphics card. This fansink quickly transfers heat away from the GPU to lower temperatures by a whopping 15°C in comparison to reference design boards. Besides this extraordinary cooling capacity, the fansink operates 16dB quieter than generic designed fansinks - catering to users who require maximum cooling without excessive fan rotation noise.
Utilizing any HDMI product that is not approved may result in poor performance, and can even void the warranty on other HDMI enabled hardware. Therefore, the "HDMI Certified" ASUS EAH4670 series - which supports native HDMI, truly are the most trusted graphics cards for home theater enthusiasts.
Keeping in line with ASUS' rock solid promise for quality, the EAH4670 series comes with several solutions to deliver top quality graphic performances. The LF PAK MOS guarantees more efficient power with less heat generation; while Japan-made solid capacitors lower power loss for more stable operations - even under long-term usage. Additionally, the EAH4670 series also comes with EMI shielding to reduce 66% EMI interference - producing more stable signals; while DIP spring chokes lower temperatures by 5-10°C in comparison to traditional toroidal coil chokes. Thus, users will enjoy extreme graphical performances and retain peace of mind with the ASUS EAH4670 series.
