ZOTAC just announced announce the world's first Quadruple-display capable ZOTAC GeForce GTX 460 graphics card. The new ZOTAC GeForce GTX 460 3DP enables multi-monitor computing with up to four simultaneous displays from a single graphics card for enhanced productivity, gaming and multimedia.
The card is capable of driving up to four independent displays simultaneously with a combined resolution up to 6400x1200.Three DisplayPort connectors enable the ZOTAC GeForce GTX 460 3DP to support resolutions up to 4800x1200 across three independent displays for true spanned triple-monitor computing. A dual-link DVI output enables connectivity to extreme high-definition displays with the ZOTAC GeForce GTX 460 3DP for connectivity to a single monitor at resolutions up to 2560x1600 for users without DisplayPort capable displays.
Though 2D might be fine, but 3D rendering at such resolutions with just the one card is a serious no-go performance wise ... let's just hope that at least SLI is properly supported with these custom resolutions. Also bare in mind thet the GTX 460 can go maximum 2-way SLI.
