Unless you want to play very old games like from 10 years ago or something. But even so... as suggested by others I don't think it's a good idea to invest money in such an old computer. It might be better for you to try to save a little more for a new system. Even a cheap entry level one nowadays will give you much better performance than this.
BTW, I used to have an Athlon 3000+ and I've been holding on to it for way too long , I replaced it 3 years ago or something and it was about time, I should have done so even before. When it got to the point I couldn't even watch HD porn in streaming I was like, ok time for upgrade! Lol!
