I thought about paying the extra money for the OC to 120Hz+ models, but after I got three of them, all i can say is 2560x1440 is a killer resolution. I have them at 7680x1440p normally and 8080x1440p (Bezel Correction) while gaming and benching, and I dont think id be able to afford to get just 2D Surround to 120FPS on maxxed settings.
Heaven 3.0 on Maxxed out settings and just 2x AA on 8080x1440P with windows Aero on, and on an overclocked 690 (1178Mhz Clock 6900Mhz Memory) it hits 1900-1950MB Vram and I get an average of 35FPS on it. Its playable, but is not ideal.
On 5760x1080 with everything maxxed out even AA at 8x, it only uses 1500-1550 MB VRAM and it gets around 55-60 FPS.
So having said that, you would need Quad SLI 680s/690's to even get 60+ FPS on 2D Surround with Heaven 3.0, just to meet the standard 60Hz quality. Its not even an issue of VRAM, it just lacks the pure brute force to push that res on the monitors.
But I can say, the difference in picture quality between the 1080p and 1440p is very noticible. Its amazing and crystal clear. It looks alot better playing on just "High" Settings at 1440P than playing on "Ultra" Settings at 1080P for sure.
Just a single monitor I think will be fine with 1 or 2 680s =) But I like surround haha. Maybe the upcoming Flagship 685/780 whatever they decide to call it, will have enough power in Quad SLI to get these closer to 120 FPS to make the 120Hz worth it in surround. Id have to save for a couple years to afoord that =(
I know benching and gaming are totally different, but I just used this example because it is a good baseline that people can compare performance with when using different setups or what to expect from their hardware.
