Please edumacate me about Ryzen / AMD systems. I know only core 7 era Intel stuff. What's the newest thing on the AMD block. Ryzen? Pending releases? I'm not interested in overclocking (too busy with other things to bother) - will be doing some photoshop, video editing and gaming. The thing that interests me most is that if I build a modern system from scratch, AMD may be a cheaper option. Maybe. Obviously I'd want a thoroughly improved decent step up from my current i7 4770K Ta.
