I've got what I suspect to be a failing MSI Z170 motherboard, the build is as follows, Intel 6700K Corsair H100i GTX MSI Z170 SLI Plus G.Skill 2x16gb 2x EVGA GTX 1080 Ti Samsung 850 EVO 500GB Samsung 950 Pro 256GB EVGA 1050W PSU Cooler Master MasterCase Pro 5 I've been looking at two options, Intel 7900X ASUS TUF X299 MARK 2 Corsair 4x8GB Or Intel 8700K ASUS ROG Maximus X Hero The idea would be to reuse as much as I could from the previous build, but with the idea of moving up in performance. I was able to get the pair of 1080Ti's for $750 each before Christmas with the idea of having a better chance at 3x4K as I have 3x 43" Vizio 4K 60Hz TV's as monitors on my desk currently. I'm a sysadmin so the usable area to work especially on patch nights is very helpful also. I understand the bottleneck of anything on the Z platform having only 16 PCIE lanes with running an SLI setup, but my questions are more of the idea that I play AAA games, edit photos, and general use. Is the investment in the 7900X worth it as far as gaming performance goes? I know it unlocks the full potential of the SLI setup, but is it going to be THAT noticeable of a difference over my current setup when it was at its prime? Or is it a safer bet knowing what I'm doing, to save the money and stick with a Z370 combo? Any assistance is appreciated, thanks in advance.
