Not sure what you mean by it having enough horsepower. It has a strong 3d engine but besides that, there is no mention of onboard MPEG2 decoders (which is what you must mean by horsepower in this situation.)
It has hardware assist like a lot of other cards, but its main standout is going to be the quality of the vide it outputs. That being said, if you get a fast enough computer, you can do HD decoding in software.
