This card can receive an audio stream from a sound card to transmit it via a DVI-to-HDMI adapter. If this feature is important for you, make sure the adapter is bundled.

This card requires two additional power connections: 1 x 6-pin and 1 x 8-pin. So you may want to check the bundle for an 8-pin power adapter as well.

This card features an original TV-Out interface, so an adapter is required to output video via S-Video or RCA. Such adapters are usually bundled.

This card requires a DVI-to-D-Sub adapter to be connected to an analog monitor with a D-Sub interface.

Maximum resolutions and frequencies:

• 240 Hz maximum refresh rate
• 2048 x 1536 x 32bit @ 85Hz Max - analog interface
• 2560 x 1600 @ 60Hz Max - digital interface (all Dual-Link DVIs)

MPEG2 playback (DVD-Video) was analyzed back in 2002 and little has changed since that time. Modern graphics cards do not load CPUs during video playback by more than 25%.
