It's not bad, especially for the price, but it will struggle with more intensive games. Easily maxes out Source games and COD at 1920x1080, but you won't be able to max out any DX11 games, especially if you have the DX11 features enabled. Couldn't say about other games, as I have 2 cards now, but there's plenty of reviews around. Don't forget, the 5770s are good overclockers, so there's a good bit of extra performance in them. They are, however, mid-range last-generation cards, so don't expect to be maxing out those new releases.
