I have a friend with an older computer (P4 3ghz, 1gb ram), and I'm trying to get him and his wife set up with their new HDTV a few feet away, so that they can use Hulu and and Netflix streaming and perhaps do basic web browsing and what not on their TV using a wireless keyboard/mouse instead of using their antiquated 1280x1024 monitor. The machine itself is fast enough, even with its present integrated Intel card, to run basic video including 720P HD (it struggled only a bit when I tested a 1080P copy of How to Train Your Dragon), but what concerns me is that the machine only has PCI expansion slots. Would a PCI video card, say a Radeon HD 2400, have the bandwidth to output 480i/720P streaming video and stereo sound (and more basic web-oriented usage at 1920x1080) over an HDMI cable?
