Overall, the proposed build is poor to middling:
- Mobo: Overpriced. A $140 AR
GA-Z68XP-UD3 will do what you need.
- CPU: Overkill for gaming. An
i5 2500K will perform very similarly and costs a lot less.
- PSU: Way overkill on wattage. A
Seasonic M12II 620W is higher quality and costs less.
- GPU:
Not worth it IMHO in a world of $450
7950's.
- RAM: Who knows? Not enough detail given to make a determination
- HSF: Not worth $100 when a good tower cooler like the
Mugen 3 is $50.
- HDD : Fine, but I think the items above saved you enough money to get a
128GB m4 right off the bat.
