I want a computer that can play games like g-mod and day-z at good graphics and I want to record while I play and I don't want that affecting my game by lagging. Also I don't need a big hard drive as I have an 500GB usb hard drive. Is this a good setup I'd like to stay under $600 Canadian. So is there any thing I should change about this? http://pcpartpicker.com/p/3h7zHx
