Get a decent gpu , i would say get an 8800 but the model depends on what money you wanna spend
Get enough hard drive for your needs , what you think you will need
And a decent PSU
ALso depending upon what you already have you may need a new case
Those are just example parts i dont know how well they work at all as i dont have them and so i am sure other people can come along and show you what would be better
