I have a Q9550s, 8GB ram and 4870x2's and I run smoothly most of the time. The game has come a long way and runs smoother now than when I first played the first iteration of it! You should give it a shot again, anyone here will be willing to help you with any issues you might have once you get it going. I just got a few of my friends to join us so our numbers seem to getting a little larger and I have seen more people on!
