Is this a good build?



They don't work on PC as well.

OP please use PcPartPicker and list all the pieces your build has there and post it from the [bb] section or the permanent link.

Better and cheaper.
 
Well I'm not sure if you're just trying to show a start or what. A power supply CPU/motherboard is not a computer at all. It's less than half of the price of a decent gaming computer. If you'll give me a budget for your whole build, also do you need a monitor? Keyboard? Mouse? Headset?
 


For the most part, yes, that is just a start. I have already ordered a different power supply: CORSAIR CXM series CX850M 850W
I have also already purchased a case now: https://www.newegg.com/Product/Product.aspx?Item=N82E16811353034
I already have a keyboard, mouse, headset, 2 monitors - 27" hdmi & a 24" Vga, and a graphics card I am going to transfer over into a new midtower case I bought. since my budget is about $300 into the build at this time. My graphics card is quite outdated and is the AMD Radeon HD 6770. I am under the impression that the CPU I listed can serve as an APU and would be able to assist the graphics card to help FPS until I can buy a new graphics card. If you are able to shed any light on my thought process that would be great :)
Thank you sir!
