New Pc build is underperforming

[Cassy108]

Hello good people:
My system looks something like this:

1 SSD 250 gb
1 HDD 1 TB
2xZotac gtx 1080 ti amp extreme(i found out too late that they are the worse for sli because of high temps,but i put an external fan on them and the upper one stay at 80C so i guess is better than 90 before)(maybe reducing the clocks on them keeps temps down)? Imo the boost on the extreme cards is not worth it but what is done is done...
DDR3 1600
I7 3370
Gygabyte Z77X UD3H
1000w PSU
Gaming on Asus Rog Swift PG348Q

With these 2 graphic cards and on ultrawide i get lower frames than on an 4k monitor.

Example would be Witcher 3 that has 70 80 fps compared to 100 110 as i have seen on youtube.

So i am guessing i still need to upgrade,but i do not know witch motherboard ddr4 and cpu should i buy.

I hope with those 2 card i may be able to hit 60 fps when the 4k ultrawide monitor comes out.

Any feedback is welcome,thanks

You sure you're not talking about the i7-3770K and not the non-K suffixed processor part? Also the processor on your post looks like a typo. Regarding your system, what is the capacity of your ram? More rather, what is the ram kit you own? Pertaining to an upgrade, what sort of a budget are you looking at?

My bad,early in the morning and was not paying full attention:
I7 3770 non K 3.4 Ghz
16 GB ram Corsair Vengance
Water 3.0 240 Cpu cooler with 2 fans
Corsair rx 460
Budget up to 1000 in case is worth it.

Thanks for reply ^.^
