At this point I’m basicallly just going to wait for 2020 to shop for a new CPU.
Thankfully I already have some decent systems, but if I only had an older CPU right now I would be mad.

Looks like it’s going to be a while before Spectre can actually be dealt with properly.

I really wouldn't worry about it if you wanted to buy a new computer.  If there is a difference in Photoshop or Lightroom, it's immeasurable. 

On the other hand, frankly, the practical difference between a 6, 7, and 8th gen desktop i7 and between a new $300 processor and $1,500 are all relatively small for PS/LR, as long as you have plenty of RAM and SSD.

In Photoshop or Lightroom, I think I actually notice caching to m.2 SSD's more than I notice the faster CPU speed.  The problem is that everything that is sluggish in a 3 year old PC is still sluggish in a brand new, 8700K with all the works, either before or after the Spectre/Meltdown fix.  So things I wish happened faster (even if it's only a couple of seconds) are still that way, and frankly, I can't tell the difference between 1.9, 2.1 and 2.4 seconds (that would be generations of PCs)... they're all irritatingly slow. 

And... everything else is instant.

IMHO, for PS/LR stuff, if you have a Haswell+ processor, I wouldn't bother upgrading unless you know you'll get a very specific benefit, because even though the processor is certainly faster/has more cores/etc, it isn't going to FEEL any faster.   If you play demanding 3D games (or want to mine bitcoin...), you'll get more mileage out of buying a GeForce 1080 than anything.


And now even GPUs are affected!

Sad, isn't it?  But basically, anything that has speculative execution and where arbitrary code can run is probably affected to some extent :'(

So what does this mean for secure internet banking and other 'private' operations

If, for example, you do a virus sweep then open only your chosen browser (IE, Google, Mozilla...) then go onto your banking website will you be secure?
