What is it a Facebook PC? If all you want to do is surf the web you can drop the graphics card and drop the PSU to a lower watt unit, remove half the RAM and go with a much cheaper motherboard. should save $200.
Was just looking for a replacement for basic graphics and the A10-7890K with Wraith cooler looks good. That way you don't even need to buy an aftermarket cooler. Since it will be a small system like that, you could even go with a tiny case.
Honestly if you are looking for any type of gaming proficiency, that build is not it. It will play games though, just not that well.
It is possible though that I am being too harsh. But I am not so sure. For gaming at 1080p I wouldn't go with anything less than a R9 380 or a GTX 960. 16GB of RAM is cool and all, but it is a waste unless you are doing some very memory intensive task, gaming is not one of them. 8GB of fast DDR3 is a great balance here.
Now the CPU you selected is just basically obsolete. If you insist with going with AMD right now, the FX-8320 is the minimum I would recommend. it is a hot chip though and slow compared to even low end Intel chips (but intel does cost more). It has issues running anything more than a R9 380 or a GTX 960 without bottlenecking.
Get Windows 10 instead of 7. There is absolutely no reason to buy an ancient OS. If you don't like 10, find a good build of Linux instead. Linux has come a long way and is much more user friendly, if my mother can use it effortlessly, you can too.
