Before using nvidia fx5200 128MB im using Geforce4 mx 440 64MB.What confuse me is i try using benchmark on both of this card the result is that Mx 440 is running 310fps but the fx5200 is only running 181fps.While playing 3D games i can feel that fx5200 is slower than mx440.I had already download the lastst driver from nvidia homepage.Can anyone one pls tell me why ?
