Feedback on my gaming computer

you are VERY unbalanced. The 650ti isnt really a very powerful card. You are overspending on the PSU, Case, MOBO, CPU.

for half this budget you could build a more powerful gaming PC.

You should drop to an i5 3570k, cheaper mobo, MUCH cheaper case, PSU from a reliable company such as Antec or Corsair.

use this extra money to get a 7950

your build right now will only get you medium/ high settings in games. If you do what i suggested you could max most games.
