So I was looking through Newegg during my 2nd period and came up with what I thought is a decent build for a little less than $700.
For the CPU I went with an FX8120 due to the price. You can get one for $120 from Newegg right now. I imagine with a 500Mhz OC (Which isn't to much to ask) you should be around 8150 performance. So a 7500ish on Passmark which isn't bad for the price.
For the MOBO I went with an ASUS M5A97 which is just a good board. Should be just fine for overclocking as well.
The SSD is a Kingston HyperX 3K 120GB which is very cheap right now at $79.
The GPU and RAM don't really need an explanation. It's a Sapphire 7950 3GB and 8GB (4X2) of G.Skill Sniper 1866Mhz. The Power Supply is an EVGA 500 Watt which should be enough for this system.
There is an aftermarket CPU cooler, it's just a basic NZXT tower cooler. The case, also by NZXT, is the Source 210.
Overall the build comes out pretty cheap and the parts are interchangeable. Feel free to tweak it.
