SLI x16 x16 question

Jeremy Driscoll · Oct 8, 2013

Quick Question: Does running SLI at x16/x16 have any measurable FPS gain over the normal x8/x8?

Context: I am building a new system and will be gaming at 1080p, but on the new 144Hz Asus monitor so I would like stable 100+ FPS on high/ultra settings. Going with 2 GTX 760s in SLI (never going to go 3 or 4-way sli), an i7 4770k overclocked as high as I safely can, and considering a ASUS Z87-WS mobo. As usual, any suggestions on the build are welcome - favoring performance more than value, but value still matters a bit.

Well you won't be able to get 16x in SLI with a Z87 board. 8x 8x at PCIe 3.0 and an additional 8x (or 4x 1x 1x 1x slots) slot that can't be used for SLI.

You would have to get an X79 board and a LGA2011 processor to have a go at dual 16x. Would be a fairly expensive board.

No, not worth the added platform cost, you wil get more by just running 2 GTX780s in 8x8 than you would running 2 x GTX770s at 16x16.

For a little clarity: I am considering the http://www.newegg.com/Product/Product.aspx?Item=N82E16813131998 mobo, which is the ONLY LGA1150 mobo that I have seen that claims to have dual x16 capability. I am definitely going with 2x gtx 760s as I have already ordered them, so I was just wondering if the dual x16 is worth the extra $100 over the typical x8/x8 mobos, with the same cards?

Not worth it, no.
That board support 2 x PCI-e 2.0 in 16x16 OR PCI-e 3.0 in 8x8.

Makes no difference to be honest, you will be happy with a board at half of that cost.
