Usage: World of Warcraft, Battlefield 3, League of Legends and HD videos obviously.
Resolution when gaming: 1920x1080
Amount of monitors: 2
Overclocking: Maybe (I have never done it and never really given it any thought)
Crossfire / SLI: No
Other: Needs to fit into my care and preferably better than stock cooling
By the way, these cards (7950) can reach about 40% higher speeds when overclocked! The most overclock friendly cards
Hope I helped you.
we don't know how old the psu is he has a i5-760 for god's sake psu's degrade over time so instead of putting out 550w or power it could only be putting out 510w which will make that psu be overused and lose even more life
