Looking at that card.... perhaps the question you ask is because you want to run 4 monitors off it?
In our teleradiology work we need to run 4 monitors from each HP workstation, and we have been doing that with xw6400, xw6600, xw8600, Z400, xw4600, Z600, Z620 and recently Z640 workstations. We use the two PCIe x16 slots in these, and drive 4 monitors with no issues easily. We do use two Quadro cards for this.
Those cards include pairing of pretty much any Quadro 2-port card we want. Low cost and fast: FX1800 for the side colors plus FX3700 for the central grayscales. Faster and more expensive: Quadro 2000D x 2. The D means they have two DVI outputs, but the regular cards with one DVI and 2 Display Port outputs work fine too (use the DVI and the next up PD port in that case). Faster and more expensive: Quadro K2000D x 2. But, all work fine. The central two grayscale monitors are either 3MP or 5MP Dome monitors, and the two side monitors are generally NEC high end 2MP color monitors. I'll sometimes have the far left monitor be a 3MP color.
I run the far left monitor as the primary (where BIOS screen shows) from the primary card's primary port (bottom port which is nearest the motherboard) from the primary slot (top of the two PCIe x16 slots).
I always use the nVidia Quadro ODE drivers (the default) for this purpose because they include the special medical grayscale drivers.
Is that what you need?
