I also one up the cooler master hyper 212 evo, that is what i run in my pc. Also titanHunter is correct(hey again), you will NOT be able to max out games like that with full anti aliasing, again as was already stated, you will be able to play high settings with no AA. as for my parts list, which is over budget, but this what i would do if you actually wanted to max out these games to ALMOST the fullest extent at 1080p.

Now all you need is a nice mid tower case and your set, again I know this is way over budget but this leaves you with loads of options in the future and kick-ass performance right out of the box(once you build it). Given that you buy an Intel k version processor, you have the ability to overclock, this processor and board can hit 4.2 ghz easy which is plenty fast for any games right now(3.4 ghz is fast enough at the moment). And if you dont want to go through the trouble of overclocking yourself, you can use the oc genie msi motherboards provide to do an automatic overclock, though it is recommended you do it yourself. The graphics card is a beast as it is and xfx makes great coolers, this card performs just under what a gtx770 performs but the 3gb of ram over 2gb will help with the rendering in a game like arma 3, also giving the 280x has a bigger memory bus actually taking advantage of all the memory. Again, you can overclock the card to outperform a gtx770. Just make sure if you do overclock that you have proper cooling in your case. You can also add a second 280x in crossfire in the future, if you ever plan on doing that, get an 850 watt power supply to save money in the long run.(Also, if you can get a 770 for cheaper, that would be another solid choice, just keep in mind you will see some advantages in having 3gb of ram, such as gaming at higher resolutions.
So all in all, if you want to wait(by the sounds of it you dont), i would save your money and do a build something like this, it makes you up to date with the latest socket and provides you with solid performance in games and options in the future.
