Like the tittle says, what components do you recommend me to upgrade? My setup is as shows from my user profile.
Wanting to play the latest games coming out! or at least to keep up with them, budget wise around 600-800 bucks? Ideally I don't want to spend that much though...
The only things I would upgrade from those specs would be the PSU first. Get a decent Corsair, Silverstone, Seasonic, etc. A 750W Corsair Gamer Series are pretty damn good and can be had for peanuts. Then maybe after that upgrade that GTX660 to something with a little more grunt. A 280X or even a 290 custom cooler will do you nicely. If not those then a GTX770 would give you a nice increase. After that for some "free" performance get a decent after market CPU cooler if you don't already have one. Something that will fit your case, maybe a single AIO water cooler like a H90 or H80i would be a good place to start. The overclock your CPU to at least 4.2GHz easily and get some decent performance increase. Other than that your pretty good with what you have. You will only need to upgrade that CPU to eith a hyperthreaded 3770K or a platform change to X79 if you plan on doing a lot photo, or video editing or 3d modelling work. Otherwise for everything else you have a pretty nice rig already.

Use that CPU cooler wisely and overclock that CPU a little to 4.2GHz at least which should be pretty easy. That H80i should fit most cases, if its too thick then go for the H90 or a decent air cooler.
An upgrade of PSU is recommended, as already suggested. 750W is, indeed, a good wattage. To spend as little money as possible, I would suggest considering doing SLI. Grab a cheap GTX660Ti and the pair will give a significant performance boost.
I'd like to throw this one in as a suggestion http://products.ncix.com/detail/msi...dmi-dp-pci-e-3-0-video-card-69-86111-1051.htm it's a bit cheaper than the 290 and is faster, and yes you need to update your PSU.
