"no my friend it will not as always the bottleneck is the monitor....i dont know of one with a refresh rate of more than 120 at a res of 1600x1200....when i can get a monitor and a graphics card that can do that and run games smoothly, then ill be impressed......you could always disable VSYNC but that causes tearing (at least on my comp)....
forget monitors....the ultimate bottleneck...our body....your eye will not tell the difference between 80fps and 180...."
then run your monitor at 60Hz. your eyes still cant see all of the 60fps, right? and describe what tearing looks like? and also imagine running a geforce3 at 2048x1536x32 with all options on max? youd get not many fps, LOL. a geforce4 will give you 50% more, might be enough to make it smooth
