CPU vulnerabilities are better dealt with through hygiene ("know your code") than more complex CPUs.
Are you actually a target / have something worth stealing on your computer?
Are you actively working with malware?
Are you running nightlies rather than Stable?
If you answered "no", these 'flaws' are probably not going to affect you.
Right now, I'm more concerned with one of my SSD or hard drives failing, because it would currently cost ~4X to replace them.
I had a DDR stick develop a fault, and fortunately was able to replace it before the RAMpocalypse was beginning to crest. My two-years-out-of-support machine also didn't require bleeding-edge memory.
