So I want to build a new computer for less then $500 USD

I have a video card an AMD 7870 which will do for now. I do not need a keyboard, mouse, monitor or OS - I'll probably use some variant of Debian Linux and will dual boot a Windows Insider build on Windows 10. Normally I answer these type questions but I wanted to see what creative designs some of you could come up with.

I may play some games on it but not to often. I'll also be web browsing, some programming with Visual Studio (small projects), browsing the internet, some light office program work using LibreOffice, streaming video such as Youtube, Netflix, NBC and CBS All Access.

I do know I want a quad core CPU if possible with this budget. I may begin purchasing parts tonight or tomorrow.

BTW - I'm ok with purchasing parts from multiple online sources and I have a Micro Center nearby.
 
Solution
If you are wise you will drop that power supply like a bad habit. It's your system, but power supplies are not a good place to skimp. If that power supply goes out it can take out your entire system.

I've fried a motherboard before due to a cheap power supply. It may be ok, but you only saved like 20 bucks. But it's your system.

If you upgrade the video card ever, I would recommend to replace the power supply at the same time.

Edit, I see you are going to use a 7970, so if you can, definitely cancel the power supply and swap it for something better. Otherwise, hopefully they've improved those units since the last time I used one of them.

For future reference, to bad you ordered the CPU/board online. Microcenter usually gives...

My friend is letting me borrow his ASUS 27" 1080p 144Hz monitor and a AMD 7900 Video Card with 3GB RAM

Yeah I ended up buying it all at Microcenter, which is why I ended up with this particular power supply. I plan to aggressively update the lesser parts as funds become available. I'm using core temp to track the temps of the CPU, but I'm not sure I am getting accurate results. Can any of you recommend a more accurate temperature monitor.
