desktop with 4 monitors

Question

I am looking for a home office PC for work that runs at least 3 and preferably 4 monitors (2 of which are high resolution monitors). What kind of video card will be needed to get me 4 video output ports? I assume the video cards will carry memory to support the monitors, but would additional RAM (going from 32 to 64 GB) would probably help as well?

In addition to a video card that has 4 output ports, also look into monitors that support daisy chain.

You have several other options, in addition to those mentioned by @ProfessorW00d.

GPU that supports 3 monitors and an onboard Intel Graphics port for 4th one.
If the PC's onboard Intel Graphics is DP++, a DP++>MST hub can support 4+ monitors. Some MST hubs support a mix of both DP and HDMI outputs to monitors.
GPU that supports 3 monitors and USB3>video dongle for 4th one.

More RAM is always better. Windows sets aside some system RAM for use by an add-in GPU. An onboard Intel Graphics port uses only system RAM.

You also have to keep in mind what/any GPU may be factory installed. If the available OEM cards don't meet your output needs, would you be willing to buy/install an "after-market" GPU? For Dell XPS 8960, the latest XPS desktop available, the graphics card specs are listed here.

But that raises another issue: PSU size. "After-market" GPUs tend have higher minimum PSU recommendations than Dell OEM GPUs, even when the cards have exact same NVidia or AMD number. Obviously, Dell wouldn't install an OEM GPU that needs a higher wattage PSU than they would install, but a larger PSU may add to the price..

For XPS 8960, the options are 460W, 750W, and 1000W PSUs. IMO, a 460W PSU is on the low side...
