You don't say what card you have or what's wrong with it, but you can find
info about ATI cards here www.rage3d.com
Can't tell you where to buy them in NL, but I can't imagine it would be that
hard to find a computer shop.
Sorry but am going to assume English is NOT your native language but what
card died, what kind of card do you want and there are lots of online as
well as retail stores that sell ATI cards.
