I have an old computer (Dell Optiplex 380) an want to add a second screen for my security cameras. I need a PCIe graphics card that has no need for a power cable. I found this one: GeForce G210 PCI Express 512MB DDR2 Video Card HDMI, DVI & VGA Output PCIe PCI-e and wanted to know if it will work out for me. I don't play any games really, I just watch youtube, check my email, and serf the web. I now want to add the second screen to watch my security cameras on. I have an extra monitor that uses both VGA and DVI-D. Will this work?
