Benchmark Results: Crysis 2 (DX 9 And DX 11)
The Crysis 2 charts place Nvidia’s GeForce GTX 690 about as close to comparable as you can get to twin GTX 680s without matching up exactly. That’s reassuring for anyone who might have been apprehensive about giving up a few megahertz compared to two GeForce GTX 680s in SLI.
AMD’s Radeon HD 7970s in CrossFire show well at 1920x1080 and 5760x1080. However, even with Catalyst 12.4, they continue exhibiting a disturbing (and reproducible) crash at 2560x1600 in DirectX 9 mode.
6990 aren't that hard to find. Back in January before the 7000 series came out, you could easily pick one or two up. I am pretty sure in 6 month, the 690 will be easy to grab.
