This card has two BIOS chips and a switch to select one. This should help avoid unsuccessful firmware upgrades. The first chip is select by default.

This card features its own audio codec, so nothing else is required to output audio to HDMI.

This card has two 6-pin supplementary power connectors.

This card can work with three monitors simultaneously (one has to be connected via DisplayPort). Moreover, each new DisplayPort 1.2 interface allows outputting signal to three monitors by means of a special hub. So two such interfaces allow connecting six monitors at once.

Maximum resolutions and frequencies:

• 240 Hz maximum refresh rate
• 2560 x 1600 @ 60Hz Max via digital interface (all Dual-Link DVIs)

We thank AMD for the provided graphics card.
