I was thinking, while tom's is doing their system marathons, we can have a little fun of our own. For all of the people that give their advice on this forum, I bring you the $300 build challenge, basically you have to provide the links for a sub $300 gaming capable system (rebates count), the parts that have to be named are CPU, GPU, Mobo, Memory, and Power supply (other parts like coolers are welcomed, but not mandatory). I did some light browsing on newegg on my own and came up with a little something, if someone tops me then I'm sure to come back with an even better system!
