As the title says should i sell off my 2 MSI 580 lightning xtreme editions for an evga 680 classified? or MSI 680 lightning xtreme? I dont really use SLI anymore actually with the games i play and only really got SLI for BF3 and Crysis 2. Now that i dont play those games and only use one of my 580 thought of getting the 680 as its faster single card. But then again i also do still play BF3 here and there and want to maintain more then 60FPS at 1080P all settings maxed.
