I am planning to build a gaming PC that will also function as a home theater PC in the early part of next year. Currently I use an HP 2311x monitor with an HDMI connection and a 60 Hz refresh rate. I want to go with an LED display between 36 and 40 inches in size, that has a 120 Hz refresh rate. However, my research revealed that the only way to achieve 120 Hz is to either use a Dual-link DVI or Displayport connection. None of the LED TVs that I looked at on Amazon, Newegg, and TigerDirect had those connections and the 40 inch computer monitors are over $1,000. Seeing as I may only be able to use an HDMI cable, would I notice a visual difference in a PC game such as Star Wars The Old Republic or Mass Effect 1,2, and 3 on a 120Hz display compared to a 60 Hz display or should I stick with a 60 Hz display?
