Ok, I finally got a new card to repace that onboard GeForce4MX, which was good to play Sim City 3000 and The Sims for a while, but now, it's time to move on.
And the new card is.... Drum Roll.... nVidia GeForce FX 5700 (non-Ultra) by Leadtek. I decided to play safe and get this lower-powered card, but the performance is pretty good so far. At last, Flight Simulator 2004 looks as Real as it Gets.
