It will make your games run faster yes, but as The Sack says, the system you have now will last you quite a while. I have a similar setup myself (except i have 2000xp, but every item is the same as yours) and there is no game that it will not run. The only time you'll need to get a new video card is when games like Doom 3 and Half Life 2 are released, but that's not for a few months yet. If i were you, I'd hold on to your current system setup, and upgrade come august time, when cards like 9700 will have come down a lot in price. Or wait until the next generation of cards are released.
