Looking to Skylake for my home server build, mostly because I'm fed up of waiting. I'm planning to stick with my i7 960 in my desktop for a while longer though -- I'm hoping it'll keep me going 'til Cannonlake, it's still holding its own for the moment.
The next desktop upgrades I'll be looking at will be based on driving 4K @ ~90fps for VR; I'm hoping that we'll see that become a possibility with NVIDIA's Pascal flagship. For the moment, my GTX 970 is giving me all the performance I need at 1080p, I may step to SLI 970s if I can find a 4k G-SYNC monitor to suit.
