I'd think really hard about whether or not you need an OC'd CPU. CPU performance doesn't have a lot to do with video game performance, and combined with the aftermarket cooler, it takes up a lot of your budget.
If I were just playing video games, I'd use a locked i3 processor and spend the rest on an SSD or GPU. I just recently began running BF3 on a samsung 830 series and it loads in no time compared to a 7200RPM HDD. Another benefit of not OCing is that you can save on the motherboard by getting an Hxx or Bxx chipset. 99% of motherboard differentiation within the gaming market for $1000 builds is just marketing.
Here's my recommendation:

caveat: after looking at Crysis 3 benchmarks and how heavily it is affected by CPU performance, 2 observations:
1) You may want to swap that 250GB SSD for a 120GB model and put the extra $100 into an i5 processor. 2) you need $2k ($1250 for the computer, $750 for the monitor if you don't already have at least a 1440p screen) if you intend to run Crysis 3 the way it was meant to be played.
