You know what your old system has and can do or won't do. Now compare that to a new basic/entry level PC from the likes of HP or Compaq. Now, review any games requirements will be and match the system to those requirements.

You've been gone too long, so nothing is salvageable(to a degree) from old system other than back-up system. A basic system now has at least duo core cpu, 2gb ram, 256mb video(video card) and refrain from "on-board" video and all the ports needed plus win7. That alone makes the upgrade worthwhile.
