Have been looking at this cool NVIDIA Quadro FX 560 128 meg graphics card.
Basicaly you can have two computer screens be it VGA or DVI to spread your timlime out over and then it has a 3rd output through a tiny Video Breakout Box which enables simultaneous connection to HD or SD component, S-Video, or composite video/TV displays while you edit.
All for like $350 AUD....I'm going to get one and try.
Don't stop with just 128mb ram on the card. Get a card, either ATI or NVidia PCI-E or AGP, 256mb ram, 512mb. Many of the latest video editing software uses GPU processing power for HD.
