Your GPU will be the limiting factor of your system. I recommend at least an HD5850.

I have a 22" Samsung. 50,000:1 Dynamic Contrast, 1920x1080. My budget is around 200$ but if its really necessary then I will consider spending more.

is the DIAMOND one better or the XFX one better? the diamond doesnt seem to have many reviews on newegg while the xfx one has plenty.
