Sorry for the bad news, but this system is not futureproof. It looks good, for a small budget. I don't think you need an after-market cooler, unless you intend to overclock. In that case you need better RAM too.
What kind of PSU did you pick? Can you afford a decent 500W PSU and an x1950xt? That would be a lot better and it could handle new games for a while.
