Option of Choosing between dual or single GFX card solutions
I've found from past experience I'm not a lover of the struggles of dual graphics solutions, it caused more pain than gain. Personally I think you should provide an alternative single card solution too when dual graphics cards are suggested.

Great, thanks for listening! I think it will prove useful in the long run as I found when using SLI, a lot of games required fiddling with the profiles through Nvidia inspector, which takes time and patience to perfect. Some people just want to play the game! :D I'm glad you understand this.
