you can go dvi to hdmi which would get you the best picture then you would need 3.55 stereo headphone jack adapter to phono and then normal phono cable to an audio input if available on tv. If not then you can get pc to scart kits which will use the svideo on the gfx and normal audio output

If the tv has a digital audio input ie coaxial or optical and you pc has spidif output this with the dvdi to hdmi will be the best
