My friend just upgraded his video card from a Geforce 2 MX to a Geforce 3 Ti500 and while his games run a little faster, they still lag quite a bit. For instance, Warcraft 3 begins to lag when a lot of units appear on screen and start fighting. He has Windows 2k installed with the current detonator drivers (40.72). He's currently running a P-4 1.5ghz with 128mb of ram and scored about 4500 on the 3dMark2001 video score. Would increasing the ram help?
