Very good, but for gaming i7 has no advantage over i5 so if you're going to be gaming get an i5 4670k and save the extra money for other things. Aftermarket water cooling is only recommended if you're going to overclock, so if you are not overclocking consider a Cooler Master Hyper 212 Evo or Thermalright True Spirit 120M which are both essentially air coolers that are quite and keep your cpu with low temps. The motherboard, ram and PSU is good. I suggest using the money that you will save by following my recommendations to buy an SSD. The read/write speeds are amazing on an SSD, performs 5x faster than a hdd and makes no noise at all since it has no moving parts inside of it. A 256gb or 128/120gb SSD is recommended for OS drive and use the WD blacks for storage (games etc). The monitor is alright, but as far as for gaming aim for 1920x1080 monitors if you really like that dell monitor go for it, I'd personally get an ASUS one but it's up to you. Lastly you didn't mention a DVD Drive, these are very cheap usually under $40 and could serve you well in terms of gaming unless of course prefer Steam/Origin or for future proofing in case maybe you want to watch a movie.
^Agree if you have not got the parts yet consider the i5 4670K and put the extra money into something else or just save the money off of the build.
For a CPU cooler I would look at the Cooler Master Hyper 212 EVO they are really good coolers and come in a a good price. And as said I would use the money saved by going with a i5 for a good SSD for your OS drive.

oh sry which is good i7 4770k or i5 4670k in rendering
Both, I'd say get the i5 4670k bud you won't regret it. If it's not too late, I'm not a salesperson of AMD or anything but if you chose to go with AM3+ and got a FX 8350 which is 8 cores at 4.0ghz it's the best bang for your buck. You can get it for three times less than the i7 4770k but if Intel's your choice then go for it.
in reality, there are only 4 physical cores. and 2 threads per core. so beware that you will only get 4 cores. not 8 cores. its a con. selling 4 core cpu as 8 core. AMD has poor benchmarks. intel is costlier but it has much better performance.
Just get whatever fits your budget, I recommend FX-8350 but if you want to go Intel than get it, but just a heads up though that AMD has never failed me. Switched from Intel to AMD and love the performance. Not in my position to say either, but do get an AMD video card instead of a nVidia one, because AMD's new api Mantle (DirectX and OpenGL alternative only for amd cards) will be used to run console ports from PS4 and XBOX ONE so obviously you'll have good performance and good graphics with the AMD GPU.
