Now i see what you mean about scaling. These cards do not scale what so ever going from 2 to 3. Dizamn!!!
Didn't know you had already bought a third card, I thought you already knew they scaled terribly.
I found out Months ago when I originally tried 3-Way and 4-Way SLI with an additional two more KPE's after testing with the first two I bought!......Hardly much improvement at All and sometimes even a Loss running Benchmarks!
There are only a Few Tests I ran that show any reason (Fire Strike Extreme, and perhaps Mark 11 Extreme and Vantage Extreme presets) for using more than two cards in SLI, and I Now am thinking even with more than two GTX 980's (??) there will still be the same problem with scaling.
It even may have been better using two GTX TITAN Z's in Quad SLI, But even I am Not going to take a chance spending almost $7K for two Hydro Copper Z's Just to Find Out! LOL!
So, spend the $7k. LoL.
Out of curiosity, and only that, what would happen if you installed 4 gpu cards? I know SLI would not work, but, could the Dual gpu be used for Folding, Mining, and such? I don't know what I thought about that, but it am curious if a 590/690 could take advantage of the 8 gpu cores in total.
