I Got a Hauppage HVR-1800 for christmas, and am planning on attaching a 17" to my current gtx 280 and 24", with the 17" for tv while I do other stuff (surf net, game). I am wondering what kind of performance hit I'd get while playing games and watching tv at the same time. I play a lot of games from 5 year old wc3 to crysis warhead at high settings. I have never had a tv tuner before.
