2x 8x or 2x 16x SLI 980Ti

[Anthony AKA Salmon]

Moving to the US and then getting new PC by moms company for a max amount of around 2300$ and getting SLI 980Ti so I wondered do I need 2 16x PCIE slots or is 2 8x PCIE slots fine? cause I am getting 4790k and it has max 16x of PCIE slots. If you guys want you could link a build from prefferebly same company!

Thank you in advance, Anthony

EDIT: When I wrote this I was watching Linus video about PCIE slots and noticed in hes benchmarks there was no difference, so I guess 2 8x slots are fine?

Either slot is fine and there will be no noticable difference.

The difference is only 1-3%, so not really worth the ~$200 extra you would have to pay for a motherboard with a PLX chip on it or the $600 extra cost of going LGA2011v3 with an i7-4930k and DDR4 to get native dual x16 slots.

X8/X8 is what you will get with a normal Z97 based motherboard.
That is entirely adequate.
Unless you will be gaming on a 4K monitor, a second GTX980ti is probably overkill.

Sorry I missclicked answer but Im going to be gaming 1440p 144hz G-Sync ROG Swift, and I have a question, how should I setup the perfect setup,

1x BenQ XL2411Z 1x ROG Swift 1x BenQ G222HDL

Or

1x Rog Swift, 1x BenQ XL2411Z, 2x BenQ G2222HDL

and comment in what way I should set these monitors up, I want to mainly game on 24'' and games such as tomb raider, witcher 3, batman on the ROG Swift.

Put your best/strongest monitor in the middle and make it the primary monitor.
Not that many games support triple monitor gaming.
For the rest, games will be directed to the primary monitor.
If you really can't decide, do some experimenting by switching them around.
