For those who struggle with frame rates(jerky screens) then you really should invest in a reasonable graphics card.
Assuming your motherboard is Pci express and not AGP you can pick up a 8500GT for under £40/$80 these Days (Amazon/price runner) this card will run any Casino software at excellent frame rates.
Monitors do not effect fps(frames per second) and the speed is measured in milliseconds for the time it takes the monitor to refresh the sreen.
8ms ia acceptable but 5ms or less these days is better.
Most people probably wouldnt notice the difference unless displaying detailed fast moving graphics(usually games)
