Don't laugh but I have used a VooDoo2 (Monster II) card for over 4 years without an upgrade. I am not that much of a hardcore gamer but I do play Half-life/Counter-Strike when I have the time. I know it may be obvious but how much of an improvement should I expect? Will it be like night and day?. I am impressed however with the quality of the voodoo2. I hardly have any slowdowns when playing CS and the picture quality is really good to my standards.
