You'll want to see what the current systems have in them, and what kind of hardware they support. For instance, if they're all Pentium 4 or Celeron based with motherboards that don't support more than a 400 or 533MHz front-side bus, they're probably going to be decent machines for playing high-definition games at best; they'll probably be better off as general purpose machines for the average user and not the gamer. Newer boards with 800MHz front-side busses are going to be a better system to build on, though these machines would need to run at a minimum of 2.5 ghz to be decent performers for what you want it to be.

I would make sure every machine had the realistic minimum of 1GB RAM, though 2GB or 3GB would be more realistic to offset the slower overall system speed.

With the video boards, You'd be looking at a minimum of an nVidia 6800 or 7600, or ATI x1550 based video solution with 256MB of Video RAM to get decent frame rates; 512MB is always better than 256MB in this area too.

Finally, if these computers are coming from corporate environments where they were left on constantly, you might want to look at replacing all of the power supplies; office computers are notorious for having power supplies that don't go along with upgrading the computer. With the upgraded video cards, you'll probably want to go with something that has at least 350-400 watts; more can be better, but for these systems, anything over 500 watts is total overkill (unless you can find high-output power supplies for less than the cost of a mid-range power supply, then more power to you...no pun intended).
