What video card will work on my computer?

My computer is an eMachines T3508 I have Windows XP, right now i have a ATI RADEON XPRESS 200 Series card, what will work on my PC? I would like one that is not a lot of money either, and preferably one from Newegg. What is a good one?|||Like the previous poster said any PCI-X card will work fine, depending on how much you want to spend I would recommend a Radeon X1650Pro for low end, and the Radeon HD3850 for the higher end.|||Any PCI Express x16 card will work. But you have a Celeron processor...so don't expect too much!
