The 9800GTX+ Black Edition is a highly overclocked 9800GTX card and should perform as such in all the latest games. Crysis is the hardest game on computer hardware at the moment as it brings everything but the most high-end cards to its knees. The 9800GTX+ Black Edition is able to play this game quite comfortably at a 1280x1024 resolution with frame rates in the high 20s throughout. Two 9800GTX cards can play this game quite comfortably at 1680x1050 with High settings enabled and is actually as fast as a single GTX280 card.
The Unreal Tournament PhysX Mod pack is a series of maps that have more advanced physics effects due to the PhysX software in them. Unreal 3 Engine allows the use of PhysX software to have destructible walls floors, and a Tornado that destroys the battlefield as the players play. The 9800GTX+ plays these levels at playable framerates up to 1280x1024. Two 9800GTX+s in SLI play these levels up to a 1600x1200 resolution. Any RTS or RPG game will have absolutely no problem playing on this card at maximum resolutions, its only on the more demanding FPS games that need the most power that slows a single GTX+ down at all, and in SLI these cards are hard to beat by any current game title or test software.
