Well I have a GeForce 9500GT. I have no idea how to overclock anything. I just built my first computer over the summer so I guess I would be called a beginner. Anyhow, I was planning on playing Call of Duty 5 and World at War on this new computer. I also wanted to play on full settings (maximum resolution, etc.). I downloaded the trial for Call of Duty 4 before I bought it and I turned the settings all the way up and I got a slight lag. Is there any way to overclock this graphics card so I can play this game on full settings without lag? If so, how. (Remember I'm a beginner....so start at the beginning).
