PC is for work and play. So if I decide to upgrade, I'm going x99. Just to give you a general direction where I'm going gaming wise, I'll eventually be upgrading my monitor to the Asus PG27UQ 4k 144Hz once released. Some general info: Just upgraded From Win 7 Pro Was using 2x GTX 780 Ti's Mobo: Rampage IV Extreme CPU: Core i7 3930k @4.4GHz The 3930k seemed to be a perfect cpu for my old 780 Ti's. Being that I'm moving up to 4k, would it be wise to upgrade my mobo and cpu? With my 2x 1080 Ti's, I'm sure I have the GPU horsepower, but I just worry my Mobo/Cpu combo could hold them back.. Also note that the 3930k sandy bridge are native pcie 2.0, not 3.0.. Could my mobo/cpu keep me going until Intel releases its next enthusiast class chipset (i.e. the x299)? I can pull the trigger at anytime for a new mobo/cpu/memory..
