i7 is of no use for gaming or light application use. i7 2600k is for heavy multi-threaded applications due to their hyper-threading technology. i5 2500k is THE best intel chip for gaming at $220. the GTX is the best choice for a SINGLE monitor setup, whild a 6970 would be best for a triple monitor setup, dual if inside your budget. Asrock makes a kickin Z68 GEN 3 MoBo, and an HX1050 would be highly recommended for any of these options. 8GB of ram is plenty for any gaming system. Get a good case teamed with either (with this budget if you are OC'ing) a Noctua D14 or a Corsair H100. Great cases are Cooler Master HAF 932/942(X), as well as Antec 900, NZXT Phantom. Go with a Full Tower.
