What is the difference between the two highest video memory sizes ?
How does it affect performance.
I have set mine to the second highest as I only use one external 1900 x 1200 monitor and I prefer to have the additional memory for system RAM.
More memory is required for higher resolution and colors. You should leave it at 128M since your using 1920x1200. You can increase multi-applications performance at the cost of lower your share video memory.
