About to start a new PC build based on Skylake: Asus Z170 Deluxe i7-6700K GeForce 780 (may upgrade this but no SLI plans) Intel 750 PCI-E SSD (400 GB) Parts list at: uk.pcpartpicker.com/p/CsvqZL (can't post links yet). It occurs to me that the OS and apps will take a big chunk out of the 750's 400 GB, so I'm now thinking I might get a 256 GB SM951 for booting Windows and installed applications, leaving the 750 for the other things I need fast storage for (VMs and databases). However, the PC will also be used for gaming, albeit not SLI. Given the 20 PCI-E lanes supported by the i7-6700K will the two PCI-E SSDs plus an x16 graphics card cause a bottleneck?
