Best video card for playing movies?

When I go to buy a video card, what should I look for in it(box), to know, that I'm getting the best picture possible during videos playback?



I don't want to spend the extra money on graphics that won't enhance movies/videos playback such as video games...or other related stuff.



And also how much of a difference (picture wise) will it be from the manufactures' video card?

Will I notice any drastically changes on my movies?



My PCs info:(I bought it back in 2004)

Compact Presario S6700NX

Intel R

Pentium 4



I got it connected to a Samsung HDTV.
