Minimum Nvidia for Dual DVI 1920x1440 Monitors
We want to put dual 1920x1440 DVI monitors on some of our workstations.
We have nVidia geforce 6800 cards installed, but unfortunately these appear to be limited to dual 1920x1200. What is the minimum nVidia card required for dual dvi 1920x1440? Our applications will be primarily business applications, so geforce may be overkill. -- W |

(that's a single DVI connector) Check your card and cables. |

This table hasn't been kept updated. http://www.nvidia.com/object/extreme_hd_gpu.html You can also look at specific cards here and see if they have dual link DVI. http://www.nvidia.com/object/geforce_family.html It helps if the workstations are modern enough to support PCI Express cards, as throwing "AGP slot only" in as a requirement, isn't going to help. If you can use modern cards, odds are good of finding more solutions. Ultimately, you buy the card from a card manufacturer. And you have to verify they're offering two dual link connectors on the card. The card manufacturer could save a few pennies, by cutting corners, so in that sense, the NVidia tables aren't a guarantee. They're an enticement. This table, gives you a rough chronological order of introduction, so you can identify the modern versus ancient cards. You can tell from the MSRP column, whether the card is expensive or not, and whether it's a candidate for a cost effective upgrade. http://www.gpureview.com/videocards.php Or, you can go through a list of cards, sorted by price. http://www.newegg.com/Product/Produc...CE&PageSize=20 This one has a PCI Express main slot connector, and two DVI available. $75 It's a marketing gimmick, that it has to cost $75. They generally charge a bit more for that connector configuration. If you want the cheapest card possible, generally you don't get to choose the connector configuration. So $75 is getting two DVI at the moment. EVGA 01G-P3-1431-KR GeForce GT 430 (Fermi) 1GB HDCP Ready Video Card http://www.newegg.com/Product/Produc...82E16814130609 Then, we have to check it supports dual link DVI. And by some miracle, I can actually confirm that. In many cases, even with a downloaded spec sheet from the manufacturer, they can't seem to capture the important features. This time, I got lucky. http://www.evga.com/products/pdf/01G-P3-1431.pdf "Two Dual-Link DVI-I HDCP Capable Connectors" That card won't be a power-house of 3D processing power, but it will run a stock trading screen with text on it.

How do you think a GT430 dual DVI would compare against an older gaming card like GEForce 7900GTX dual DVI? For most 2D applications and simple video playback I guess there would be no noticeable difference? What would be typical energy consumption for both cards in a business application setting (no gaming)? Your posts are really really helpful and comprehensive. Thanks. -- W |

The 7900GTX is listed here. 31.2W at idle. 51.5W in 2D peak (no gaming). http://www.xbitlabs.com/images/video...00gt_power.gif The GT430 is pretty low power. 2.7W at idle. 13.5W in 2D peak (no gaming). http://www.xbitlabs.com/images/video...b430_power.png This benchmark result was easy for me to get. Getting good head-to-head benchmarks, using the same processor and game for testing, is a lot of work, but gives better quality numbers for comparison purposes. At least this should dissuade you from replacing, in the name of getting a higher frame rate. http://www.videocardbenchmark.net/high_end_gpus.html GeForce 7900 GTX 728 GeForce GT 430 692 The most powerful card in that list, is about 5x more powerful.
