I second this - I'm running an old 5200 thru DVI to a 50" Rear Projection

Picture quality is awesome - DVD Playback/TV/HDTV (via HD3000's) all is

One word of advice - plan to use powerstrip and Windows (on another drive)
to get the timing for X right.......once you do - you'll NEVER go back.

Well I'm running a Gigabyte 6600 GT over DVI. If anything, the quality is
good! I'm driving a 50 inch RP DLP. When you blow standard def DVB
up to that size, you do sometimes notice compression artefacts (blocking and

ringing). I know there are some filters that should be able to reduce this. 
Also some of the channels over DVB-T have a bit too much compression. Other 
than that the picture is fantastic.

Put a HD clip on (The DivX Sharks Tale trailer is a cracker) and you'll 
fracture your jaw on the floor!
