Budget Gaming Rig - Under $1000

Yeah, so I have been looking into getting a new computer for a while now, and I would like some opinions on what I plan on getting. I want to spend under $1000, hopefully including the monitor. I'll show you what I got so far. The hard drive and power supply concern me the most, but still would like an opinion on everything else. Thanks in advance.

Hey PatsFan, Welcome to the WTT Forums. It all looks fine to me so far. The PSU should be more than adequate and you shouldn't run into any power problems. If you're planning to overclock, however, it might be worth going up to 750 W or so. The hard drive is also a good choice. If you have any spare cash it might be worth looking at an aftermarket CPU cooler. It will keep your CPU much cooler and ensure its longevity. Good luck with the build! Nahumi
