your monitor's age doesnt effect on the performance or fps, its mostly what resolution your screen is, heck i have a 6 year old 20 inch 1680x1050 screen which is working perfectly
You guys on the forums are the best!!!
I'm getting 100+ fps on crysis 3 on low settings, on my HDTV... I guess it was that old monitor after all.
Time for a monitor upgrade.
