On the license I have a Retail, that type of license can I use it again?
Sure can! Retail licenses can be used again and again - as long as you uninstall it from all other systems. It can only be used on one computer at a time.
I'm a big fan of Ryzen as it's really pushing Intel to innovate and finally release cpus with more than 4 cores. Intel has been pretty complacent over the last few years since they've had no real competition and it's great to see AMD back on form.
I agree completely about competition. As consumers, we need AMD to keep nipping at the heels of Intel and we need Intel worried and constantly looking over their shoulders to see what AMD is up too.
I am not so sure Intel is being that complacent - at least not on the R&D side of the house - where they can be very secretive. They got spanked, embarrassed and totally humiliated by AMD in the past by being complacent, smug, if not arrogant and got caught sitting on their laurels allowing AMD to leapfrog right over them. It took almost 10 years for Intel to regain momentem and leapfrog back with their Core 2 Duo and they promised themselves (and their shareholders) they would not let that happen again. And fortunately for Intel, they have the deep pockets to stay ahead - if they don't get cocky and make the same mistakes as before.
So while AMD may release a processor here and there that really shines, when it comes to the entire production line of offerings, Intel still has the advantage and I believe, Intel has the capability to surprise us all, if necessary, by releasing a product/family that puts AMD back in their place at just about any time Intel wants to.
What is really hurting Intel right now is all this bad publicity over these chip-level security bugs of late. While the bugs certainly are serious, it is sad how the IT press and others have exaggerated the threat to ridiculous extremes making it seem as though every Intel user everywhere was, or would be soon infected. The facts are, the vulnerability is very real but the measures required for a bad guy to exploit it make it nearly impossible. In fact,while malware has been discovered out there designed to exploit these vulnerabilities, to the best of my knowledge, not one computer anywhere has.
I have four different disks.
Typically, and for the most efficient setup, RAID uses identical disks. With different disks, the speed of the slowest and size of the smallest generally determine the speed and size of the resulting array.
If me, I would go SSD.
