I would like to setup 2 dell 30" displays on my pc, however the monitors only support Dual Link DVI connectors.
I have a budget of $400 and I am happy to add a 2nd video card or replace my existing card.
core 17-920, 6gb Ram
850w truepower psu
Radion 4800 series card - GV-R487DS-1GD.
I would prefer to stick to ATI Radion Cards.
I generally use this for office applications and video editing, less so for hard core gaming, but I would like to push both displays to 2560*1600
This Dell monitor has display port , hdmi , dvi and D-sub.
A lot of the AMD/Radeon/ATI cards have one dual link dvi and one single link dvi. All of the newer Nvidia cards have two dual link dvi but they are not good for two monitor gaming but they will support the extended desktop. In sticking strictly with AND you could get a display port to DVI adaptor to connect the second monitor and the good thing about the newer AMD cards is that they have 3gb of video ram which comes in handy with the 30" monitor and 2560x1600 resolution.
Are you crrently using one of the 30" monitors and want to add a second or are you getting the two monitors together and wanting to set up them with your computer?
The video card that you have now has two DVI dual link connectors , Have you tried to connect them to the card that you have? You can use dual cards if you want if your motherboard has another x16 slot for it.
I believe that the 30" monitor and 2560x1600 resolution will want to have more than 1gb of video ram on the card to support that resolution. The card that I had linked has 3gb of video ram and would be a good choice for that setup. If you don't want to spend that much then you can go with a 7850 since that also has 2gb of ram and is less money. You could also get a DVI splitter to plug into the one dual link port and connect to the two monitors or you can go with an adaptor.(display port to DVI)
I don't know if you will be able to find a second 4870 ATI/Radeon video card to add to your system. Like I said the card you have has two dvi dual link ports but the card only has 1gb of video ram and I'm unsure if that is enough for two 30" monitors at 2560x1600. If you are able to find the second 4870 and want to go with it over the newer card then that will be a choice for you to make , I personaly think that the newer card with 2gb of video ram will be a better choice.
