True. I have 10-year old Athlon II X3 435 so you can imagine my possibilites. :p
There's also Ryzen 5 1600 AF which is basically Ryzen 5 2600 underclocked for 100€.
That's what I'm running at the moment, great value indeed. I run mine underclocked to 3GHz at 0.85v (yes, you read it right) all 6 cores stressed at under 80W at the wall...
If you want to overclock is easy to get 4.1-4.2GHz stable, at stock it runs 3.7 on all cores, so it's not far of a 2600... The cooler may need a upgrade if heavy loads are used with overclock.
Had a phenom II X4 955 recently (gone now) and the performance difference is dramatic, even web browsing, specially using a NVME SSD.
Only complains I have so far are motherboard related, performance is great but I tend to value quality engineering over RGB.
Not yet found anything that wont run good, only Playstation 2 emulator can use a little help from core affinity (runs good but more accurate emulation require a lot of single thread processing power).
And contrary to many peoples thinking, this is not AMD related. Can get 20-30% more fps on some games and much less stuter, by playing with core affinity on a Intel 4-core Atom device.
If Zen2 Apu's turn out to be good, I may change the 1600AF for a APU. Graphics performance will probably stay close to current gen, due RAM memory limits...
