Will a I5-4960k really bottleneck two 1070 (SLI)

[1stbuild46]

Hello,

I'm aware that an i5-4690k is not the latest CPU on the market and that it's not an i7 yet do you feel like it would be a waste of money to pair this cpu with two GTX 1070 in SLI? I read that (2X 1070) SLI would be too demanding for my CPU and would cause GPU throttling but that a single 1080 would not be as bad, can you explain?

I used to have 2 GTX 970 in SLI with that processor and never felt like it was holding me back.

I wanted to sell both of my GTX 970 to get something way faster but a single 1080 is not that much of an improvement... However, i won't put $1000 in two GPUs if my CPU is holding my back...

CPU: i5-4690k
Mobo: Asus Z-97A
Ram: Gskill16 gb DDR3-1866
SSD Samsung 840 256GB
GPU: GTX 970 -----??? (SLI 1070 or single 1080?)
HDD 1TB
Windows 10

Thanks for your advice.

It will only bottleneck them in specific scenarios like 1080p on 144Hz monitor, but not to a degree that would really affect your gameplay.
You'll be fine.

Thanks a lot.

What about if I play at 1440p - 60Hz? Do you foresee any issues other than in a few games like arma 3, GTA 5 which are (I think) CPU bound ?

Arma 3 might give you some trouble, but that's because it's poorly optimised and even an i7 would behave teh same. GTA V, no issues whatsoever.
