Just as a matter of interest your graphics card has twin DVI outputs and an S Video output, exactly same as this one except its an XT1950? You will have a DVI to a D Sub adapter for analogue monitor use.
What this means is if your monitor is capable of receiving 720p? it should have an HDMI input, 1080I or what Blue Ray uses 1080P, you can transmit HD with a DVI to HDMI adapter + 3M of male HDMI to Male HDMI. you still need RCA stereo from puter to the RCA input on other monitor. Thats how i can get tv recorded on hard drive via twin digi tuner or DVD playback.
Same cpu as this an E6600 but this is a lot better and quicker all round in spec, this struggles if trying to do something else as well as video playback GPU, CPU 2.55Ghz all day, RAM, FSB all overclocked. Could try overclocking dead easy and bomb proof on these, your weak link is ram and mobo, GPU okish.
