As graphics cards go, it still holds up fairly well [http://www.hwcompare.com/9783/geforce-9800-gtx-vs-geforce-gtx-550-ti/] when you compare it to some of the new-ish cards, but give it a few years and you probably will have to replace it. For example, I've replaced the 8600M GT in my laptop (EDIT: I've replaced the whole thing with a desktop, that's how) because that's not going to be able to run most of the newer games soon, and it can't run some well now, but given that the 9800 GTX is a FAR better card than the 8600M GT, it'll still be useful for a few years to come.
