Yeah I saw your site earlier today but my only concern was shipping? Because I'm really trying not to go to far over $600. Also would that build perform better than the Cyber Power? (Damn do I feel like a noob)
Get the $500 build with a Core i3 2100. With shipping it should stay under $600 (most of the stuff have free shipping anyway). There is a 1+ hour video on my blog (from Newegg, not mine) on how to build the PC yourself.
To get the same performance from a prebuilt PC expect to pay ~$200 more.
