Well its a good mid/high area performance card.
Its usually best to post full system specs when asking a performance based question because while its a decent card its no good you looking at buying one if the rest of your system is not a decent match for the card.
Here is a full review of the card http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_560_TOP_Direct_Cu_II/1.html
While a 560 Top would be fine in general at 1920 x 1080 it would fall short in the more demanding games. So if you want to run the newest games at 1920 x 1080 then i would be looking at a 6950 or a GTX 570.
