Umm ... before you go running off buying a card based on one persons advice ... first off, you're going to need to determine what slot type that card is, cause it originally came in AGP, PCI, and PCI-Express 'flavors', and therefore it must be replaced with a card of the same slot type.
Can you take a good picture of the card in the PC, using a flash or bright light, so we can see the slot it's plugged in to? If the board doesn't have a PCI-Ex slot, it's seriously not worth upgrading the card because I don't think you can find a decent AGP or PCI card anymore that doesn't cost a lot more than it's worth.
Lastly, let me just say ... I literally cannot believe it's still possible to play ANY game on a 64MB video card still. Are you at like 800x600 resolution with everything on the lowest possible settings to get that to run or what?
Wait til you get a new system, you're gonna be amazed at the difference ... that card wasn't even a good gaming card in 2004 when it came out, let alone nowadays ...
