Quite easily, with my rig (can see in my sig) I'm near maxing out Crysis 3 at a stable 45-60FPS.
If your just gaming, drop the CPU down to an i5. The i7's Hyperthreading has no real impact to gaming performance.
Drop Windows down to Home Premium 64bit, Professional is only useful if your going to be using more than 16GB of RAM.
850W is a bit overkill, on that rig a good 650W would do. If your going to Crossfire later on, get a 750W
That Green drive also isnt ideal, but there are some things you can do.
Use the money saved from the above to get a 120/128GB SSD for a boot drive (holds Windows, important programs) and use the Green as a storage drive (movies, music, files, unimportant programs and games).
Or replace it with a faster drive like a WD Black or Seagate Barracuda. I suggest you go for the Seagate drive, perform just as well as the WD Black and are often a lot cheaper. Or do both
