Does this system need overclocking?

Im going to buy a custom PC soon and was wondering whether or not I actually needed to overclock it to play games like Crysis 2, BF3, ARMA II and others on maximum setting at a good steady framerate? Im getting the Sapphire HD radeon 7970 GHZ edition. Which I believe is already slightly overclocked.

    Depends on you if you want to make it more better then overclock upto 4.2ghz with stock voltages in this case your cpu lifespan will not decrease otherwise No, i7 at stock speed are enough for gaming.
