The ATI 600 USB is one of several recommended devices (the Elgato isn't isn't in that group). Obviously the #1 choices are All In Wonder AGP and X-series AIW PCIe, but they require XP. DV devices aside, which we constantly warn against and which won't give you a lossless capture, here are some others:

A caution about
Amazon reviews: Most of them are from clueless users who have no idea what they're doing and aren't capturing to lossless media anyway. I recall reading bad reviews years ago about the excellent AIW 9600XT Radeon AGP, one of the best AGP cards around back then. Fortunately I ignored them and got my info from a tech site. and still use that card 12 years later. There are plenty of examples of work with recommended devices posted in this forum, including many of my own. There are also examples of godawful problem tapes, for which you need a good card, a good player, and some post processing skills. Capture is only the first step, seldom a finished product.
You didn't mention an external frame-level TBC, which you're likely to need as well.
