It depends on what you are using the CPUs for. Even with the latest and greatest games they may or may not use more than 4 Cores. Also mind you it is taking game devs a good while to utilize more than 4 Cores. So I think the 7700K may hold up for alot longer than you realize. Also what do you need alot of PCI-E lanes for? The only uses for the PCI-E lanes would be SLI graphics cards and PCI-E SSDs.
