ghosting and frame rates
Well guys actually the gpu or framerate wont make any difference in regards to the screen ghosting.
Suppose that your are playing quake and your flaming new ati card is pushing it at 250 fps at 1600 X 1200, but your screen have a max refresh rate of 60 hz at that resolution.
What the refresh rate means is the number of times that the screen is redrawn in a second, so if you are maxed at 60 hz that means that it can only display 60 fps
With lcd screen what can actually make a difference in ghosting is its response rate, in other words the time that the pixel takes to switch from one color to another.
therefore ghosting won't improve or get worse with a new gpu since the response time is not related to software in any way.
hope this helps
