I'm upgrading a Dell Vostro 260, at my office, to use as a design computer. The software requirements are "Graphics card and monitor capable of at least 1920x1080 resolution at 100% (96 dpi)". I've got the monitor covered, but this pc does not have a spare connector from the psu for powering a graphics card. Can anyone suggest an affordable card that powers off of the PCEI connection?
