You want to dominate games the next 4 years then you need to overclock your CPU in CPU intensive games like WoW.
The performance hit you're gonna get in raids will be noticeable between a 4670 at stock and one overclocked.
280X is 200 $ cheaper and roughly the same performance as the 770.
Overclocking is pretty easy, i'll post a guide if you decide to get the 4670k. Should take 30 sec to do a safe overclock.
I also don't understand how everything went to 2000 $? The builds above takes you at 1300 $ with a monitor?
Also saying it's not beneficial to have a SSD for gaming & browsing makes me want to make a petition to fire this joke.
I think it's back to the drawing board :/
