Dual super silent ventilos, games pass without pb, no bug or slowdown, some games going at high definition. of course the pure gamers will find much better but for me playing only occasionally does it work hard enough. games tested: hawkx, call of duty mw3, assassin's creed, team fortress 2, Batman Arkham Asylum, tomb raider 1-2-3, dc universe. has this price this card does wonders
