I am on a vista machine. I need a solid quad dvi pci-express video card. I will primarly be using it with large photoshop documents and complex illustrator documents. I have done some research, but there seems to be only a handful of workstation cards that support 4 dvi ports. Ill be using 19" monitors at 1280 x 1024. Currently I am using a GeForce 7300gs and 6200. I would like DX10 Support. I would also like it to be less than $500.00.

Have any suggestions?

The Matrox Parhelia's are very nice for this ... but don't meet your "... less than $500.00 ..." criteria.

This ATI card for $379.99 should work nicely IF you have a PCIe slot (it just needs an x1 slot ... so any PCIe slot is okay):  http://www.newegg.com/Product/Product.aspx?Item=N82E16814195039  

Note that it does not support DX10 (it's got full DX9 support) ... but I'm not sure a 4-DVI DX10 card exists.

Also, if you don't have a PCIe slot available, there's a PCI version of this card:

Wouldn't the PCI 1x limit the amount of processing the card would be able to do?

It's all relative.   Clearly the bandwidth is less than a PCIe x16 card, but it's still more than a PCI video card.   A PCIe x1 channel has a bandwidth of 200 Mb/s compared to the PCI bandwidth of 133 Mb/s.   In addition, the PCIe x1 channel is full duplex ... although that's not a big advantage for a video card, it does mean that any reverse channel communication doesn't impact the bus (which can actually communicate at 400 Mb/s if both directions are simultaneously active).   In addition, the PCIe x1 channel isn't shared like the PCI bus is => so other cards don't impact the bandwidth.

There are plenty of 2x DVI cards out there at 16x pci-x. If I had two cards equipped. One being a normal 3d video card and the other being a 2d video card how is the work handled? If the application is on the monitor with the 2d card, does it render using that card or is the work split between cards?

Each card is used for the displays connected to it.

Excellent then a 2 Dvi card will be just fine. Any suggestions for this card? Thank you very much!

Does your motherboard have 2 PCIe x16 slots?  ... I presume it does, since you're leaning that way;  but just checking.

... as for a good card => a pair of lower-end Quadro's would do nicely, and keep you under your $500 target:  http://www.newegg.com/Product/Product.aspx?Item=N82E16814133208   They're also DX10 cards :-)

I believe there is only the one. The other is PCI. Thanks agian.
