Well dude, what type of board do you have? Also, maybe you want to overclock the proc a bit too. Futhermore, if you do that you won't need new ram. Trust me, you are better off getting a new rig. I'm in your same position. What I would do personally is make sure you have a nice PSU. Then I would get a ATI 4850. For the price it rules. Use that to wait out a computer upgrade.
