Nothing! I am so disappointed. My girlfriend was having a bit of trouble playing her favorite game "The Sims".She experienced alot of slowdowns, stuttering and the like. We were told that even though our computer was a bit older (PII 450) that it was powerful enough to play her game. We were told our graphics card (voodoo 3 3000 AGP) was not up to par and that we should upgrade and then the problems would stop so we bought a nVIDIA X-TASY GeForce MX 420 card which has 64 meg of memory. Well, I installed the card and installed the drivers. As I restarted, I was ready to see a great improvement in graphics and speed but..NOTHING! The stuttering and slowdown are still terribly there. Have I done something wrong? Am I wrong to expect a big difference? Is there a way to tweak my card for better performance? I uninstsalled the drivers for my old card so they didn't conflict with anything the new card was installing so I'm at a loss. Help me computer gurus!
