Pretty good for a sub-$500 budget build, but there really isn't much "gaming" to be done on a $23 video card, unless you just want to run Facebook games and maybe games from 2006 on Medium.
An R7
260X ($119) would be roughly 8x-10x faster.
Also, NVIDIAs 8xx series is due to premiere next month, so the 7xx cards will drop about 30% in price by then.
