Hey bjkill, take a look at this:
I think your PC should be fine with one of these, both good for games and media center and it's a budget around $850.
Of course you can switch to another MBO or stronger CPU from the AMD or Intel series, it all depends on your budget and how much money are you willing to spend.
Since your post is from the 10th August, you probably got your new config, but still there you go the configs I gave you.
If you are having a way better config than those 2 I gave you (what you probably do as you are mentioning Formula VII MBO and the 780 GPU) then you don't have to worry about games nor anything for the next couple of years.
Honestly I am not really good with water cooling and monitors stuff, so I will stay away of giving you an advice on that.
Hope you found something useful here hehe.
