How do I know if a GPU is compatible with my OS?

[Nicholas Stoltzfus]

I'm looking for a graphics card(GeForce GTX 550 ZOTAC ZT-50402-10L) to fix my old build
but it doesn't tell me if it's compatible with my OS.

OS: Windows XP
MB: A8N-SLI Premium
CPU: AMD Athlon 64 x2

-fast update-
Thanks for the help everyone!
Just to let future 'nerds of tom's hardware' to come here know that I got a new GPU and it runs GREAT!
So no new answers are necessary.

If there's drivers on the nvidia site for that series of card with XP, then it will work

UPDATE: And....there is, so you'll be good to go with that card

Thanks!
I'll check their website right now!

You are wasting money on that video card with that CPU. You also need to check your power supply to make sure it will run the card.
A Radeon 6570 is MORE than enough for what your CPU will be able to run and is less than 1/2 the price of a GTX550. Unless you are getting the card to move to a new system soon. If not, don't get anything until you are ready to swap out the full system. Buy now, faster cards will be cheaper later and you can find the card you want now used for 1/2 the price.
