Total hardware n00b trying to replace the graphics card in Dell XPS 8500 tower, which has an AMD Radeon™ HD 7770 2GB GDDR5 with a 500 W power supply. Replacement card is an ATI FirePro 2460. The goal is to run 3 independent displays with DisplayPort connectors. Upon opening the case I was very intimidated by the 2 slot AMD Radeon, with all of the cables running from it and the fancy plastic case with the attached fan. The ATI is a much simpler card, and doesn't look like it has the same connections (presumably for power?) as the AMD, so I'm afraid to unscrew/unplug anything from the existing card. The open PCI slots are of a different size than the ATI card; I'm hoping the slot that the AMD Radeon is plugged in is the correct size. Is it a bad idea for me to even attempt this???

Operating System: Windows 8
System Manufacturer: Dell Inc.
System Model: XPS 8500
Processor: Intel® Core™ i7-3770 processor
Memory: 12GB Dual Channel DDR3 1600MHz - 4 DIMMs
Power Supply: Dell manufactured, max 460 watts
Monitors: ASUS VE228 (3 monitors), 1920x1080 each

Since the monitors have DVI and HDMI ports and so does the GPU, why not hook up two of them via DVI (of which the GPU has two) and the third via HDMI (of which the GPU has one)? That way they are all digital and should provide the same resolution and quality of graphics. No adaptors needed and you can leave the analogue, lower quality VGA out of the equation.

Yes, we tried adapters and they didn't yield the same quality across all 3 monitors. We also tried the Accell UltraAV adaptor (http://www.accellcables.com/K087B.html), but it stretches the monitors into one wide monitor, can't adjust settings so the monitors are independent...

Well, those monitors do have DVI-D ports. Have you considered getting a couple DVI cables and only using one HDMI?

Please correct me if I'm wrong but when you say DisplayPort do you mean HDMI? Those monitors don't have a DisplayPort connector but they do have HDMI.

Sorry, got sidetracked temporarily from this issue! You're right, there are no DisplayPorts on the monitors! What we actually want is to have all 3 monitors connected to the hard drive via DVI connectors. If we use adapters to convert the DVI from each monitor to the HDMI and VGA inputs on the video card, will all of the displays have the same resolution? That's the problem we had before when connecting the monitors using the available inputs; the quality of the non-DVI displays were disturbingly lacking.
