New Gaming PC - How about this?

Very good except for a few things. The H80 sucks. For the same price go with either a Noctua NH-D14, Thermalright Silver Arrow, or Phanteks PH-TC14PE. All 3 have oodles more cooling performance, and they are air oriented. As for the GPU, you can't beat EVGA when it comes to NVIDIA cards.

Looks good - but watercooling can be a pain. What's your budget?

ehm, why is EVGA better and this is H80i - not H80

my budget is about 2000$

EVGA has the best customer service around, and their build quality can't be beat. And their cards come with a special cooling system which pushes all the heat out through the expansion slots to the rear so that it does not float up and heat the processor.

I would not change anything in your build -- it looks really good!  

Nonetheless, if you follow the advice of getting an air cooler instead of the Corsair H80i, then make sure it will fit properly in the case, and the CPU cooler will not touch the memory.

Corsair Vengeance has a quite high aluminum heat spreaders that can be in the way of the CPU air cooler fan, specially the double fans configuration of the Noctua NH-D14, which is really a good cooler.

Umm, okey thanks for answer quick  
Umm u recommend any other ram  ?

Corsair Vengeance is an excellent Ram Kit -- unless you decide to go with the Noctua NH-D14, in which case you should look for a low heat spreaders ram config like this http://www.corsair.com/memory-by-product-family/vengean...

CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Profile Desktop Memory http://www.newegg.com/Product/Product.aspx?Item=N82E168...

okey, but isnt H80i good?

I haven´t found a review benchmarking the new H80i with other coolers. All CPU cooler reviews out there will benchmark the H80, but not the H80i.

The H80i is supposed to be better than the H80 -- the Noctua NH-D14 is a bit better than the H80. Now if the H80i is better than the Noctua NH-D14 I can´t tell you.

The H100 and H100i for sure are better than the Noctua NH-D14 -- both H100 and H100i cost $20 more than H80 and H80i -- but the case must fit them.

Alright, maybe I will go with Noctua... hmm  
But really can you help me decide, Fractal Design Define R4 or some other case in same price range.. please recommend to me (midi tower is a must)

For the same price range as the Fractal Design Define R4 I would go with:

COOLER MASTER HAF 922 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or

COOLER MASTER Storm Sniper http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And those are better? - how is noise levels compared to the r4?

haf 922 isnt available here(in norway) and the sniper is too expensive, like 50% more here..

You really can't get much more silent then the R4. If you have the money, go for it.

Alright   - now on-to mother board  
Should I get the Gigabyte GA-Z77-UP4 TH instead of sabertooth?

The sabertooth is overpriced for what you get. Go with the Asus P8Z77-V PRO.
