I am building my first gaming rig and trying to stay as close to 600 as possible. I have all the parts picked out here http://pcpartpicker.com/user/djbrugger/saved/XFKkcf and am just looking for some feedback. The i5 4460 seems like the perfect compromise of price and performance and the r9 280 is dropping in price because of the intro of the 285 so i thought it would be a good pickup at the current price. Any comments on the build are appreciated as well as advice for things like cooling and airflow that i would not know seeing as this is my first build. Thanks
