Why not get an ultrawide 34 in 3440x1440p monitor? Since you're planning on SLI anyway.. 3 way SLI from what i have seen doubt it works properly on most games but i m not going to say its totally wothless even though nvidia officially doesnt support it. They have some KEY thing that allows 3 way and 4 way lol . I think 2 1080s at that resolution will do fine. X99 i think is a fantastic choice if u want to run cpu dependent games with expansions and everything...sims 3 with all expansions for example lags on my core i5 6500. Maybe thats because its an older game idk. There's my two cents. Happy Gaming
