first off I be use this with : i7 2600k @ 3.8 16 gig of RAM at 1600mhz 850 Watt PSU my performance in game use EVGA precision x monitoring . keep in mind these number be WITHOUT OC . with modest oc expect a 5-10 fp increase . Witcher 2 : all setting max , ubersample off - average of 60 fp . gorgeous . all setting max , ubersample on 30-50 fp . still very playable . recommend OC to increase the frame provide you want ubersample on -lrb- not a noticeable difference honestly to I -rrb- Metro 2033 : average of 40-60 fp . probably the card 's weakest performance . frame sit at about 50 , in some area it can dip below 40 . keep in mind this be everything max -lrb- aside from AAA , and 16x -rrb- . battlefield 3 : Everything max , vertical sync disabled . Multiplayer be at about average of 70 fp . some area of campaign can vary between 45-70 . very solid performance . this game heat up my 680 to about 79c , no other game take it that hot . Crysis 2 : all setting max , vertical sync disabled 45-70 fp depend on how many explosion and wide the environment be . some of the battle location in Crysis 2 be large and require lot of memory . can notice a slight decline in smooth gameplay . very demand game , give good performance . to play this game I recommend to OC . diablo 3 : this be a driver issue im about 80 % sure , all setting max ofc -lrb- not a demand game at all -rrb- yet when I first start play the game horrible stuttering and lag for about a couple minute . seem as if it need time to catch up to the normal 60 fp I get after the initial intense lag . weird . conclusion : Stock performance be respectable . OC recommend . Mine just so happen to oc alright . Make sure to disable vertical sync as this be hinder my 680 's performance greatly until I figure out i need to disable it -lrb- duh -rrb- . do not feel the need to overclock my CPU to 4.7 like I do before . 3.8 be fine . Hope this help . Feel free to ask question .
