HDTV capture card.

hey guys,
I am really looking into getting a hdtv tuner card for my desktop. Have you guys used any or have any pointers on which is better and why.

I have an 8800gt 512 card as my graphics card.

now when I get a hdtv tuner card, will my video card be doing the decoding and grunt work, or is going to be the tuner card doing the work?

please advise.


thanks in advance.

as, a side note I have been reading about some cards..
