~11k låter rätt troligt för ett oklockat 285, så du kan vara lugn. Crysis... är Crysis. SLI är ett krav.
Kan också upprepa vad Techreport skrev.
"For 1680x1050 pixels Very High and 4xAA, the cards capable of keeping a mostly constant FPS above 55, and no framerate dips below 45 FPS (noticeable lag) are the Geforce GTX 285 in SLI, Geforce GTX 260, 275 and 285 in 3-way SLI, Quad-SLI Geforce GTX 295, the bastardized Triple-Crossfire Radeon HD 4870, and Quad Crossfire Radeon HD 4870x2.
The 2-way SLI/Crossfire-solutions of the new Geforce GTX 275 and Radeon HD 4890 both qualify as playable, but both suffer framerate drops below 45 which disqualifies them from this list. It is however worth noting that both solutions performed close to that of the Triple Crossfire Radeon HD 4870, which only barely survives the 45 FPS cutoff.
Unfortunately, the Geforce GTX 275 SLI and 3-way SLI, as well as the Radeon HD 4890 Crossfire solution also failed to change the status of our recommendation list for Very High 4x in Crysis, running the resolution 1920x1200 pixels.
The only graphics setups capable of delivering constantly above 45 FPS are still the 3-way SLI Geforce GTX 285 (albeit not by much) and the Quad-SLI Geforce GTX 295. Even then, as neither of these solutions manages to give a constant above 50 FPS score, both solutions still only manage the grade "Acceptable".
For 2560x1600 pixels, no cards on the market manages to give even a 30FPS lowest FPS, making our recommendation list empty. There simply are no graphics solutions available on Planet Earth that can run Crysis on Very High in this resolution with acceptable frame rates."
