Which is the minimun CPU for playing the best pc games?

Depends on what types of games you play, for stuff like GTA4 a quad core is necessary, RTS games tend to appreciate a quad core, but most FPS games are alright with a quick dual core. There is too much variation between games to make a generalization about what CPU is necessary, but for the most part a quick dual core is sufficient but more CPU power isnt a bad thing.

GPU is dependent on your resolution, motherboard choice is determined by your CPU choice and if you want to run multiple GPUs in the future, HDD has no effect on in game performance just load times, and 4GB of ram is sufficient, higher speed and lower latency is good but wont make an extremely large difference where as putting extra money into the GPU rather than the RAM makes more of a difference.

Different games require differen't CPU's some are better off with a higher clocked dual core while others are better off with a lower clocked quad core. To be honest, there is no limit, newer games are coming out very often and utilize more advanced graphics and etc...and it mostly depends on your resolution. Now-a days monitors support resolutions as high as 2560x1600 which will require a very powerful CPU to render everything. However if you play on a resolution like 640x480 then a weak CPU like a celeron or something will do fine. Same goes for the GPU and RAM, there is no limit, it depends on the game, resolution, graphics...etc
-Your storage device has no affect on performance of Games.
-Motherboard depends, motherboard usually takes care of itself when it comes to buying one as your choice is limited to your CPU's platform and motherboards of the same platform have the same specs except for changes such as amount of ram supported, bus speed...etc. Your motherboard just affect compatability usually, your performance lies within the RAM, CPU, GPU.
