I've had a 2500K for 4 years and unless Ryzen benchmarks are amazing and cost-effective, I'm not bothering to upgrade.
im in the same boat, I kinda pulled a weird move though. I bought a razer blade (late 2016, 1060gtx/6700hq.) and the core, slapped a 1080gtx FTW in it, and thought that I was going to slam my desktops performance to pieces. Well... I'm starting to wonder if I really did. UNFORTUNATELY, I can't think of a good way to test this.... any ideas?
