Hello I apolagize that you have been waiting for a few days but I have just recently built a gaming pc and I have learned a lot from my build.
First, The processor is great but the cpu cooler is completely unneeded. If your going to be spending 60$ on the cooler you might as well spend 30 and upgrade the actually cpu, or just take and pocket the extra 30 dollars. Also this cooler is getting pretty bad reviews about breaking down and it not functioning.
Second, Forget what I said about pocketing that 30$. You highly need to upgrade your motherboard. I suggest the I suggest this motherboard. http://www.newegg.com/Product/Product.aspx?Item=N82E168.... There is currently 55$ off on newegg.com and that brings it down to around 130$. I really like this mb and think its a great fit and will be alot better than that one. This one includes wifi card and built in sound-card.
Third, the ram is fine but i suggest this ram instead http://www.newegg.com/Product/Product.aspx?Item=N82E168....
Fourth, Your storage is good for the money
Fifth, this is a MUCH better card for the money, I usually like nvidea but for 150 there isn't much.
Lastly, there is no reason to buy windows pro for gaming
Here is a updated build that I recommend, feel free to mess around with this build and repost it! I would love to help!
