It a beast of the class, MSI latest Radeon HD 4890 offers the latest DirectX 10.1 support with CrossFireX feature ready to rock your gaming experience. The basic specs is the 1GB GDDR5 memory with 256-bit memory interface, plus a dual-DVI port connection for dual screen convenience. The basic clock speed of both Radeon HD 4890 graphic cards is at 800 MHz and they are boost about to 3900 MHz (R4890-T2D1G) and 3996 MHz (R4890-T2D1G-OC).

The latest Sony Bravia can detect when people leave the front of their television sets, so what it does is to turn into dim mode to save electricity. But although Sony was one of the first that came with the brilliant idea of a person-detecting television, Philips comes first with a computer monitor that can detect when its users are still in front of their screens.
This PowerSensor function works independently from the operating system (it disregards whatever OS you might have), and allows you to save energy. Every time the sensor detects you are not in front of the LCD displays, it will dim. It can reduce power consumption by as much as 50 percent.
One can wish that this function will be available in all monitors and television sets in the future. But I highly doubt this will be a thing of the future. There are lot of things that can go wrong with this feature including the monitor not being able to turning on when you need it to.
