sygnus, If you are building for gaming I would go with
CPU I5 3570. (K version if overclocking)
Hyper 212 EVO + (If overclocking or noise is an issue)
16G DDR3 1600Mhz G-skill or Corsair
Good Z77 motherboard
AMD HD7950/70 or Nvidia GTX670/680 Video Card
Quality 650W PSU (Seasonic/Corsair)
Case of your choice with lots of room.
1TB HDD
1 120 Gb SSD
I would only go with an I7 if you do intensive work.
