Welcome to PCHF

DVI vs. VGA, go DVI. DVI is an all-digital, high-quality interface, which provides much higher definition on the monitor than VGA would. VGA is an aging monitor standard, since it's analog, somewhat low-quality, and must be converted from a digital signal, to an analog one to pass through the cable, and back to a digital signal once it reaches the monitor. Since you have the option, I would go DVI to get a crisper picture from your computer. I'm actually about to upgrade my LCD monitor to one that has DVI, since mine only has VGA.
