That looks fine for most DJ software..
You should be able to run most software fairly easily on that – although if you start either doing a lot of sampling/effects or playing a lot of tracks at once, you may find that either you run out of RAM – unlikely but not impossible – or that you max out your CPU. As your CPU runs at quite a low speed (Presumably it does that so it doesn’t use much power?), it may max out quite easily but you should be fine..
You can have an awful lot worse than that….
