First where are you from cause different countries have varying hardware and software that may or may not be available to purchase and also knowing how much your willing to spend makes a big difference in how you configure you system. And everyone here has varying degree of experience building their own systems and software packages so they can give you their build hardware and experiences but it comes down to what do you really plan to do and how much your willing to spend. To me video and gaming are two varying degree of same principle but gaming puts big demand on getting the high quality GPU and for video that is more toward the CPU. Since I don't know what kinda games you want to play the GPU is hard to tell. CPU at least i7 or amd quad core Phenom II would be where you should start to look at. GPU would depend alot on your gaming preferences.
