What video card could my comp handle?

I have a hp media center m7060n and my nvida GeForce fx 5500 oc 256mb video card is going out, I can find a replacement but I was wondering if there is a better card that this computer could handle. It's pci not pci express and the salesman at the time said this was the biggest card that the comp could run. Thanks for any advice.|||http://www.newegg.com/Product/Product.as…

there's the 6200, and 8400gs as well.|||Graphic gards generally fixed in AGP ports( Advance Graph ice Port), it's better u buy a 512Mb NVIDIA or 1GB Graph ice card for best Performance|||The 9400gt that Mitch linked is probably the fastest one you can get.
