Right now I have a 17 inch CRT monitor and play @ 1024x768 with 85hz. I could go down to 800x600 to play at 100hz, but I hate the way 800 x 600 looks. I notice a big difference when I play at 1024x768 @ 75hz, and an even bigger difference at 60hz. There is only 10hz difference between 75 and 85 though, yet I notice it so much. So what I'm wondering is you guys notice the difference between 85 and 100hz(at the same resolution), or are there diminishing returns after 85hz where the difference between 85hz and anything higher won't be as dramatic as between 85hz and anything lower?
