connect pc to tv resolution

Connecting a PC to the TV?
Any words of wisdom on this? I connect my computer to my TV to watch all my media files stored on the TV. Am I correct in saying that I have to buy a conversion cable to connect DVI to HDMI? What would I use to connect the audio, 2 cables made man from the bottom of my sound card in my receiver? My video card (ATI X850 Pro) has a DVI connection. Do you know if / how much quality lost? Or will it be digital? My TV, a 50 "Grand WEGA SXRD Rear Projection HDTV ™ ™ KDS-R50XBR1 has a" PC input " mode. I also remember when a friend connected your PC to your HDTV, more to play Counterstrike, had to play at a very low resolution. Since the resolution My TV is 1920×1080, does that mean I have to return from the PC? Thanks
