System Usage from Most to Least Important: Primarily gaming, surfing the web, etc.
Are you buying a monitor: No
Do you need to buy OS: Yes
Preferred Website(s) for Parts: NewEgg
Location: Florida, USA
Parts Preferences: No Preference
Overclocking: I prefer not to.
SLI or Crossfire: I prefer not to.
Your Monitor Resolution: 1920x1080 and possibly upgrading to 1920x1200 in near future.
Additional Comments: Being able to play the latest games at good or great FPS on highest settings, I would like the best parts for the money. The case can just be simple and does not matter much to have lights/see through panes on it.
And Most Importantly, Why Are You Upgrading: I'm using a laptop and it's not cutting it.
If you happen to have a Microcenter in your area you can pick up a 3570k for $190 and an ASRock Z77 Extreme4 for $85 with it. The deal is shown when you place both in your cart that saves you about $75 excluding tax but again this is only instore at Microcenter
Updated the links with what my final build looks like - thanks greatly to the input you have given.
I think your build looks great, very similiar to my newly built pc (Specs in my signature). Gotta say that the i5-3570k fully exceeds my expectations, and I haven't even overclocked it yet . Good luck with your PC!!!
