will Amd fx 9590 bottle neck gtx 1080 fe sli

[Equinox_reboot]

Will my fx 9590 over clocked at 5ghz bottle neck a gtx 1080 fe sli? And Can I over over clock the two gtxs

The 9590 will definitely hold back dual 1080's, even a single 1080 or 1070, depending on the title/resolution.

Can you OC the 1080's? Well, yes. But paired with a 9590, I hope you have a quality 1000+W PSU.

Do you already own the 9590? If you don't, I implore you to re-evaluate that decision. The 9590 is a horrible CPU, with major problems getitng it stable, must have a quality 240mm AIO liquid cooler as minimum (GTX H100i) and only has 10 boards that can adequately power it.

I already have the 9590 stable as I'm using a swifttech h220 x prestige with 240mm fans water cooler but I only have a corsair 850i psu so if your saying 1000+ psu looks like I'm gona have to upgrade. I have the gigabyte g990 x motherboard.

Resolution will be running at 3840x2160 looks like I will have to upgrade to Intel aswell then. Cheers for the help Barty1884.

For 4k 60Hz your 9590 should be ok. If you we're going for a high fps (>100) then your CPU would be a much more serious bottleneck.

I not recommend that,will works well, because my fx9590 and 2 NVidia gtx 680 4gb works worse in sli. found out that sli Rendering mode to "single Card" works better than other Options.
I guess the Nvidia Driver is not optimized with Bulldozer modules from AMD.
At least you Need 70Amps on the 12V rail of PSU, i recommend 85-100 amp. (on single rail)
Ensure that the second GFx Card is on a non shared lanes PCIe Slot to get it stable, in most cases second 16x Slot Shares lanes with southbridge, usb or onboard Sound.
SLi uses much dedicated Memory and causes sometimes stuttering on soundplayback in games while heavy loads.
I look Forward to the NVidia 1080Ti as a single Card on 1440p res Monitor, or the Rx Vega with 16GB Vram.
My sys:
Asus Crosshair V Formula-Z
AMD FX 9590 @ 3.7GHz
Corsair RM850 (ist no good for cpu SLi, checking for 1200W from Seasonic soon, or new gfx Card)
32GB G-Skill 2400 in unganged mode.
2x NVidia gtx 680 4gb.
SSD's from Samsung and Toshiba.
a 13 year old Antec P182 Tower.
Creative X-Fi Fatality SB 0880.
Win10pro 64.

No, it will not bottlle neck two Nvidia GTX 1080tis in SLI but you will get better performance from AMD Ryzen or a Core i5/i7 because of DDR4 support and Pcie 3.0, but we're talking 5-15 FPS in high FPS/high refresh rate games. In 4K The AMD FX 9590 performs better at 4K than the i7 quad cores but gets beaten by i7 6 core and up. But higher fps isn't always smoother gameplay to be honest my FX games smoother and more fluid than my i7 3770K. With 3770K I get alot of frames spikes and drops which causes microstuttering but I've never had that problem with the FX and I have even swapped video cards and I still get the same results.

The FX9590 does not beat a modern i7 in any circumstances. Even against 5th gen Intel's it is well behind, look at the 1.0% and 0.1% drops http://www.gamersnexus.net/game-bench/2182-fallout-4-cpu-benchmark-huge-performance-difference

At 4k the CPU load is less than lower resolutions due to the lower fps, 4k @ 60 fps takes the same CPU work as 1080p @ 60 fps, all the extra work at 4k is on the gpu and maybe a little RAM
