-120mm cooler fan
-Thor V2 full tower case which has around 3 built in fans. -OR- any case of your choice
-Windows 7 64 bit
Also should i get
I5 2500k sandy or I7 2600k...
Remember i want to SC or OC if i get the 570
also if you know the avg fps for games with these gpu tell me
e.g: BF3, Crysis 1, Crysis Warhead, Crysis 2.
At the max
The I5 2500k with GTX 580 will perform better than the I7 2600k with GTX 570. Games don't use hyperthreading at the moment. I can't really see developers designing games that use hyperthreading any time in the near future either.
However the 570 will get 50 FPS min on max settings in Battlefield 3 at 1080p so your call. http://www.tomshardware.com/reviews/radeon-hd-7950-over...
Side note. Ivy bridge is rumored out the end of the month. I'm not sure when you are planning on purchasing this but I see you are purchasing a Z77 mobo. It'll be a 10-15% upgrade at hopefully same cost as current CPU's. It might take a bit for the prices and stock to stabilize on them though.
