First things first, what exactly do you want to use this for;
ONLY Gaming
Gaming and some (very little) video editing/streaming to twitch
Graphic intensive games or More basic games
Java virtual machine games such as minecraft
Just post if/what all the pc will be used for and it will allow us to give you a much more specialized build that might even be cheaper and perform better for you.
Ok awesome, then there are a few recommendations that I have for you. The first being that I would not spend that much on a CPU that is not going to be used that much for gaming, booting up the pc, yes, everyday tasks, yes, video rendering (like editing not in game stuff), yes, but gaming, that CPU is overkill. I might be so bold as to say a dual core could and probably would suite you best. Secondly, I personally would up the MOBO to an ATX form factor and at that would strongly recommend something that has multiple, high quality heat-sinks (example: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131851) to better cool the board as it will be very hot running games. Next, NICE GPU man and also loving the win8 support. Back tot he topic though, in addition to an ATX sized board, a larger case would help too, even with the micro atx board (just be sure it is compatible), and make sure there are plenty of fans to keep it cool. The very last thing that is just food for thought, consider maybe water cooling the GPU? Thats a very nice, well rounded build, but not so much for a purely gaming PC. Best of luck with the build and let me know how it goes/if you need any more help/want to say what you did/didn't like about my suggestions (lol too many //////).
Honestly I prefer AMD, but again, you dont really need the multiple cores and CPU power, if you want to the 6300 would be great plus its much cheaper and actually works with the board I listed but if you are sure you do not want to do anything other than game and like browsing the intranets then I would go with the pentium (i.e. no recording gameplay, no photoshop, no CS6, ect.). One like this http://www.newegg.com/Product/Product.aspx?gclid=CLvtyu_FlcACFQkIaQodOggAkg&Item=N82E16819117374&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Processors+-+Desktops-_-N82E16819117374&ef_id=U@KJIAAABJKx9jmr:20140815150634:s , maybe a bit more powerful but that should probably suffice.
Thats the whole thing is that he said purely game so an 8350 would be soooo much overkill for something like this and the extra cores/power would hardly ever be used as well. While it could hurt to have more power, why pay for something you wont use, right?
That board is a bit better, but your not going to get the same cooling quality as an ATX. Also, that was an amd board which is not compatible with the pentium or the i5.
Hey I am only recommending what I think would help, I'm no expert (or your parent lol) so just do what you think you should overall. Building a PC is all about the mistakes and fixing them and making a purely custom PC. If you dont want two, then up it to 4, 6, what ever seems best to you. Best Wishes!
The PCpartpicker Link is fine I don't understand the problem, if you do not wish to overclock the CPU than that is perfectly okay. I think most of us would agree that we'd recommend the K-Part, cause it'll help later on but overall its an excellent build. you've stated you aren't going to stream and you just want to game you don't really need an Overclock-able CPU for that. and for arguement sake, There is no Cooling benefit with getting a bigger board or smaller board. ATX, mATX or ITX it all comes down to your case and how you position fans and how airflow is taken into account.
Either Way Good-Luck with your build and Welcome to The Glorious PC Gaming Platform.
I was not saying that the form factor of the board matters in cooling it, I said that the heatsinks that are offered on ATX vs Micro ATX are larger and can make the system run cooler. Micro ATX with the equivalent cooling capacity are much more expensive than their larger, ATX brothers. It all comes down to what he wants though. he doesn't need the flashy i5 for gaming but if he wants it then he can get it. Suggestions are just that, suggestions.
Threw something together for you quickly. Not sure what kinda budget you're on so adjust as you see fit. Anything lower than a 6300 and you'll get bottlenecks with the 770. It's really up to yourself, but if you want to continue gaming on it for years to come, don't skimp out on parts.
