Need a Good Capture Card!

Hi there, (Before yo read, note that I've put this thread in another category as well, but it wasn't getting any views; nevermind replies.) If this is wrong, please let me know.

The name's Zinni. (GT = o Zinni o)

I have recently put together my first computer. I figured Windows 7 64-bit would be the best OS to put on it, so I did. It works great so far, but the only problem I'm facing is now I don't have a cap card that is compatible with my current OS. (GameBridge) - I made it work for Vista, but I tried doing the same thing with Windows 7 and it failed. Since the quality isn't mint and I have money now, I'm looking into buying a new & better one.

This is where my dilemma begins. What is a (good) capture card that is compatible with Windows 7 64-bit? Do any of you machinima-makers out there have Windows 7 64bit? If so, what cap card do you use? Is the quality good? How bad is the delay?

These questions are pretty much the only concerns I have for which product I buy. As long as it works with W7 64Bit, has great quality, and doesn't have more than 50ms of delay, I'm good with it. Please discuss. If you don't have one, but can either find one, or know of one, feel free to share your thoughts.

Thanks for any help in advance,

~ Zinni
