Looking for a gaming pc/laptop under $500?

I need a computer that can run recording software, skype, and games like minecraft with modpacks, and common steam games like day Z, GMOD, and rust, at the same time.
A desktop is preferable but a laptop will suffice for the time being. Once again this must be around the $500 mark.

Well i recommend getting the ASUS X751MA-DB01Q 17.3-Inch Laptop, QuadCore, 8GB RAM, 1TB HD $499 http://amzn.to/...to/1n0jL7o

Intel Quad-Core Baytrail-M N2930 1.83 GHz (turbo up to 2.16 GHz)
17.3-Inch High Definition Display.
1x USB 3.0, 2x USB 2.0, HDMI, VGA, ethernet port, SD card slot(SDXC).
DL DVDRW/CD-RW. Wireless 802.11N.

Okay so starting off the above two answers will now work for you. Especially that laptop. Thats a no no, but I hope you are okay with building a desktop because for that price, and what you want to do with it, its better to build one. First if you are not sure about building a desktop then go to youtube and watch videos on how to build on. There are tons. They give step by step instructions that you can follow along with considering most if not all PCs are generally the same when assembling them. Here is a parts list for around $500. But there's one problem. The price and what you want to do with it is hard to get done. So I will post three parts lists. One for the current budget, another for what's better and one thats recommended for all that you want.
