I'd either get a k model cpu and cheaper air cooler or drop down to a z75 or h77 mobo (if u r not going to overclock).
The 7970 comes with three games so that would be my pick.
Depending on how many games you keep installed at a time, might be able to skip the hdd and use the money to get an ssd big enough for them all.
Is there much of a difference between the k model cpu and the non-k? And I doubt I would be overclocking so I guess the h77 is pretty good. And yeah, I'm leaning towards the 7970 because of the free titles.
Also, which cooler would you recommend, if I even need one, that is.
