HELP choosing components for multidisplay workstation

Ola, anandppl, hope some of you will find the time to help me with this.

So here is my situation: I'm a small business owner. We deal in what could loosely be described as mechanical engineering (planing heating/cooling/gas/water/sewage/air/gases and special installations) and our tools of choice are AutoCAD and MS Visio, with ArchiCAD, Excell, Word, Acrobat etc as supporting tools. We're all used to dealing with windows, especially since AutoCAD and Visio AFAIK don't have a suitable alternative in the Linux world. I'm a bit pro Intel (at the moment) and pro ATi (also at the moment), but would be prepared to consider amd / nvidia if someone proposes a suitable setup. My briliant chief engineer is an older guy (60+) that has somewhat of a fetish for Dell (important).

Currently he's working on a some kind of a dell (dual core pentium @ 2,8 GHz (i believe), 1gig of ram, HD2xxx Radeon - that I added myself (and learned about the single slot graphic card case-imposed restriction) , 500 GB HDD, WinXP), a dell 30" lcd @ 2560x1600 + a samsung 20" 4:3 @ 1200x1600 (portrait) lcd.
In the last months he expressed a need for a third display, that he could use physically mirroring the samsung 20" (in the portrait mode, but on the other side of the dell 30" - that I found at a reasonable price) and a new DELL pc (faster, MORE RAM). Now, since we live and work in Croatia, Dell is somewhat of a luxury (in average the USA prices in $ have to be multiplied with 10, although the currency conversion is at about 5.5 HRK to 1 $, to get our Dell / other pc component prices over here) and the dell guys over here sent me an offer for the lowest priced dell pc that supports 3+ displays and it came up to 2000 EUR (2800$) which is a bit to much for me at the moment with the display cost and such (the economic crisis hits a bit harder over here, in the 2.5nd world countries).

Now, here are my questions. First of all, the dell setup the offer was made on (they named it DELL OptiPlex 960MT) had an Intel Q9550, 4 GB DDR2 RAM, on an Intel Q45 (probably BTX) board, the video card was nVidia QUADRO 450 16x, 512 MB, 4 X Display Port with DVI-I adapters. Since nvidia states those adapters only to be single link DVI and I believe I've read somewhere that the DELL display in question (i believe it's a 3007something, can check later if needed) needs dual link DVI to be able to utilize the full 2560x1600 resolution (and i don't think it has Display Ports) is this video card even usable in this situation?
The other question is this. If I chose to buy a Dell pc (to satisfy the engineer's fetish), where my base criteria would be the ability to add a PCIE X16 graphic card (for example an HD5770 or 5850 with Eyefinity, whichever would support the combined resolution of 1200x1600 + 2560x1600 + 1200x1600) and the power supply that has enough "juice" to power such a graphic card (that would have to have a mobo with that slot and the case with a rear "hole" for a dual slot graphic card plus a power supply IMO of a minimum 400W) and DIY add the before-mentioned graphic card, which Dell setup would you people suggest I go for?
To be honest, I believe that any C2D or C2Q proc with at least 4GB of RAM would more than satisfy his need for speed, that leaving the case and the power supply being the only problem.

At last, a big thank you in advance to any and all that read through all of this (I know I sometimes go overboard) and even a bigger one to those who spend time on helping me.

pozdrav

Questions regarding to Dell machines might be best asked with Dell representatives

The OptiPlex 960 doesn't appear to have x2 PCI Express 16x I believe so you cant plug in 2 video cards.

It has a card that supports quad monitors
 
ATI 100-505532 FirePro 2450 512MB GDDR3 PCI Express 2.0 x16 Low Profile Multi-View Workstation Graphics Accelerator Newegg price is $410.00 usd. Read customer reviews on this card. Buy components and build a good system for less than $2000.00 usd and this includes the firepro 2450 card. If you have to get an Italian Exporter expedite.
 
Thank you for all your answers. I know that the optiplex I mentioned has an nvidia quadro (single slot) 4 display capable video card. Now, since those "professional" type of video cards costs a bunch of money over here, I wanted to know which dell case (and MoBo) provides me with an option to upgrade the video card with a double sloted one (5850HD for example) and not double sloted in sense that it needs tvo PCIEx16 slots, but that it needs a dual slot "exit" on the back of the case and no MoBo components that stick out in the region of the PCIEx16 slot so the card can fit (and enough clearance in the case for that card to fit). The Dell reps here aren't that much of use if you try to get them to help you with choosing a dell case/setup that could be upgraded in that way ("going around them" and saving a lot of money).
So, just in case i wasn't clear. I don't want to install a second discreet video card. I'd like to buy a Dell with a free PCIEx16 slot (probably the type with the integrated Intel graphics) and then install a discreet video card that supports 3+ displays, for instance a ATi HD5850. Since that card's back "plate" is dual slotted (so that 2xDVI+DisplayPort+HDMI+air exhaust/cooling can fit), I need a case that has such an opening in the back. That's all.

the problem with that card is that it supports a maximum of 1920x1200, while i need two displays running @1600x1200 (not a problem with that card) and one @ 2560@1600 which is an impossible task for this card. the trouble with buying components the way you suggest is that i don't get a dell (which is the engineer's main criterion) and the prices for the components you list are for USA and other "normal" countries. here, everything is much, much more expensive.
 
Just one example =The Dell OptiPlex 740 mini has a a PCIx16. Installing a duel slot Card will cover an adjacent pci slot giving you only 1 additional open PCI slot plus 1 PCI express x1 slot. Dell computers most probably will vary some what through out the world. The best way to get the information that you are seeking is to find out what is legally available to you, then go to website and download the manual. In the manual it will show the mainboard layout and what slots are available. Am I assuming correctly that your import tariffs are the reason that's driving you purchase price so high?
