Anyone know a good 500$ USD Gaming Build?

Solution
Does that have to include the OS? If it does I think you'd be better off buying a cheap refurbished office PC like this:
http://www.newegg.com/Product/Product.aspx?Item=9SIA4GH2Y50488 (Xeon i3+8gb of ram)

then you swap out the PSU for a decent one and plug in a nice GPU like this:

Total comes to $500 after rebates before shipping. Although I can't guarantee that GPU will fit in that case, you may need to do some research (or just use a Dremel on the drive cage when it gets to your house)

Otherwise for $500 without OS you can do a full build like this:

Some applications and games like GTA5 will present superior performance (smoothness) w/ any Haswell i5. Even i5-4430.
Dont you think so?

The Intel quad core will greatly help with running games, plus it will "future proof" your system. Even today we are seeing games where you need to do special hacks to run them on dual cores, I don't think it will be long before you can't run them period without a quad core.

No, no it doesn't.

Hyperthreading doesn't equal extra cores. Hyperthreading means you have logical cores, but you still need physical ones for it to be a proper quad core. This has been discussed billions of times.
