Want to put together the very best, repeat best, PC configuration for large screen (12 feet wide)home cinema, where the projector is either 9" CRT (or high-end DLP or other but not LCD). Need to include 5.1 sound. The video system would simply be the finest PC to projector to screen, replacing a $100,000 CRT/Faroudja processor system. Would welcome serious proposals - so let your imagination and wishlist run riot! Thanks.
