Currently I have an AMD FX-8350 which I have running at 4.8 GHz and on occasion I pump it up to 5.0 GHz. I've had this CPU for about five years now and Ryzen will be my next upgrade when it releases this year. I think Ryzen will surprise quite a few people, including Intel.
I also have an Intel 3570K system which is my first ever Intel based PC. I built this solely because I was able to pick up a motherboard and CPU cheaply. I would never pay full price on an Intel system purely because AMD represents better value. Yes, Intel has had the performance edge on AMD for a while now, but when it comes to real world performance the extra dollars you need to drop on the Intel system are not worth it for the average home PC user.
Regarding GPUs, currently I run both a tri-SLI GTX 670 and a CrossFire R9-280X configuration. I've probably had more Nvidia cards than AMD but when Vega releases this year I will also look at upgrading to this.
Like you I have been building PCs for a while. I find that the intel CPUs are superior to the AMD. With AMD I always had cooling problems, the standard fan was never enough. My FX-8350 needed a liquid cooler to prevent that. With Intel I just use the cooling fan that comes with the cpu. For regular computing/playing games it runs cooler and never throttles compared the the AMD without a liquid cooler.
