For all other types of drywall work, an ordinary, off-the-shelf 12V or 18 V cordless drill will work. The 12V cordless can do the trick; if you want more power, the 18 V drill can easily draw screws into wood studs hundreds of times over.
It is also nice to have a clutch on the cordless drill so that the bit will stop turning at a certain point, rather than stripping the screw head. Corded drills will cause you frustration if trying to use them for drywall projects for two reasons: the cord and the difficulty of controlling torque on the drill.
