I have seen some new video cards coming out that would drive 4 monitors...
I was wondering what are the cheapest ones to drive multiple monitors at different resolutions,
So any Matrox solutions just won't cut it...
I'm not a gamer so having high frame rates in games isn't important...

Either: http://www.newegg.com/Product/Prod [...] 6814161194
$50 each, you will need 2, then set up for dualview on all monitors (extend desktop)

or get a: http://www.newegg.com/Product/Prod [...] 6814129104
$360 for a much more expensive single card solution (runs hotter too)

(note, you can do the same with 2 nVidia cards as well)(easier with GF cards, as the Control panel is better)

any 2 video cards should do it. does your board have dual x16 pci-e(hell even a x4 with open end will work) slots?

I had dual screens with 2 cards way back, but never tried 4.....but it should be ok

Ohh yeah if you dont mind one analog screen onboard video + cheap card works too, but thats a new computer too

I can attest to the simplicity of connecting 4 monitors. (we have 6 at work, soon to be 30+) 5 of which are to be displaying to 5 monitors (4 monitors, and 1 plasma) GF cards as I said are easier, just be sure to use non-SLI and load the drivers (Forceware)

(we use older Quadro FX3600's here + a FX5200 PCI for 5 monitors)

Since you have a Asus P5K Deluxe mobo and it has 2 PCI-E slots I'd grab (2) of these HD3450's. It's $112 for 2 + mail-in rebate. I would think you'd prefer an all DVI connection solution, not mixing digital connections and analog.

Unfortunately I already have 8Chan Highpoint RocketRaid 2320 so that takes my other slot.
I'm looking at a single card solution, double wide isn't not a problem and running hot is not a problem, I watercool, so I'll keep it cold.
VisionTek 900198 Radeon HD 2600XT for $359.99
almost to pricey for my blood at the moment...

Also I'm partial to nVidia. for the sole reason that every video card i have had inn the past has been nvidia. works out well when you have 5 machines in house and there is no guess work as to where to get the video drivers.

Are you cloning any displays or do you need different images? You wrote "different resolutions"... but even if that's the case a cloned display will be the same resolution, just scaled by the displays themselves. So you could use a VGA splitter or amplifier in that scenario.

If you need different images, then what about PCI cards? Not high-performance, but if you aren't gaming then you probably don't care. And that saves your PCIe slots for your RAID card, etc.

PCI is an option, but I hear Vista doesn't like mixed cards. duno.
I'm a software developer working from home, and would like to go to 4 monitor setup, and just need more screen space. So a splitter isn't an option.
the VisionTek card would be perfect... if was cheaper.
now where to find one in Canada

If You are not after framerates in games and want to keep it cheap Your best option is to go for older second hand Nvidia Quadro card on E-Bay.

You could get (2) nVidia Quatro NVS 290 cards. They use PCI-E x1 slots and you coudl get 2 of them. Each has 1 connector but can split to 2 DVI connections.

Why did you get a board with a x4 PCI-E for that freaking Raid card? haha. It would be easier with 2 x16 slots avaliable.

From what i can gather VisionTek 900198 Radeon HD 2600XT for $359.99 is my best option.
Fits my needs... just have to fork or the $ for it.
Any reviews of the card or similar type different brand?

Nvidia NVS 440 OR Asus 3870x2 TOP

Nvidia is a single card 4 port solution Analog OR Digital. The ASUS card is about to be or has just been released. Both are about the same price. The Nvidia is a workstation card and is available now ATI also makes some 4 port cards in thier workstation line. I am assuming you do not need 3D for your line of work. I would also recommend ASUS P5W64 motherboards with 4 PCI-E slots that work at x8 when all 4 are in use. I have 4 video cards hooked in to one of these MB's and it works without a hitch.

Nvidia uses the same driver for a wide range of cards from the 6000 series to the newest. That makes things simple. You can get two monitors with the basic pci-e card, then add a second pci card such as this evga 6200 http://www.newegg.com/Product/Prod [...] 6814130289
In your bios, you will have to select which card is primary for boot.

just to clarify... I'm looking for a 4 DVI output on a single video card.
I keep seeing talk of multiple video cards...

also I'm looking for cheeper not more expensive..
the Nvidia NVS 440 is $449.99 not a cheaper solution.
Asus 3870x2 TOP? if it is new then it probavbly won't be cheeper.. but i will keep my eye open for it as well

PCI is cheeper... but not a single card solution.

so $359.99 is the cheepest... hmmm

What's wrong with using a vga to dvi adapter for the second monitor on a pci card?
