We know nothing about your project requirements and that solely dictates this stuff. If you need Mercury playback then all supported cards are listed on the tech specs page for PPro. What's not listed is not supported, it's as easy as that. Outside Mercury, however, PPro still does more conventional playback acceleration with OpenGL and that is usually good enough for a single HDV stream still. If it isn't, most contemporary cards will easily smoke your current card. It doesn't even need to be a Quadro. All that aside, of course video editing has other requirements like reasonably fast harddrives with enough space on them, so in the end, the answer may not be all that easy as going out an just buying a card...
nVidia makes the Quadro cards. They only provide the chips for GeForece cards, which means the card makers get the bulk of the money from the sale of such a card. So it's no surprise nVidia recommended a card they make themselves. However, the GeForce cards routinely wipe the floor with Quadro cards in realtime performance.
Skip the Quadro line and get the best GeForce card you can afford. Stick to a card with GDDR5 memory, at least 1GB but more is better. CUDA cores is the other spec you want to look at, more is better.
You're talking a lot of money here! I a struggling student, trying to
better myself, not rebuild the world economy! I was just looking for a
basic PCIEX16 video card that I could use for one semester with Premier
Pro. I'm on a web & interactive media track and the video class to just to
torture us. But we've got to make movies to get the heck out of this class.
Dreamweaver, Flash and friends aren't as demanding.
Got any ideas for under say, oh $200-$300? I'm not a working pro yet and
food is a luxury I kind of enjoy!
Thanks for the suggestions, though. If I see any on sale, I'll grab one
real fast, to be sure!

If you are willing to give up on using CUDA cores, an ATI card costs a lot less
I just acquired a GTX 660 3 GB card for $240 after rebate. This is great card for the money I have another one in another computer. If you do not have high resolution stills the 2 GB card is fine for HD video
