Not for me. The software I use every day couldn't even run in 2009 on the fastest processor I could find. I started using it live in 2012, at a 256 sample block size. In 2015, my 5775c and SSD cut that down to 128, while allowing me to double the channels of audio. Today it runs at 64 on my Ryzen 5900. For playing percussion that's the difference between impossible and just great. For comparison, my 8700k still can't run the current version at any speed.
Processor speed has mattered a lot to me in my line of work, as well as L2 cache (the broadwell still punches so far above its weight!) --but live music is particularly unforgiving.
SSDs do deserve some credit.
To answer the original question: I have to hand it to the 5775c, which is still the second fastest computer I own, after 8 years. (although it's on its second motherboard and power supply after getting fried by a power cable short, so maybe that doesn't count. It did survive that event, though!)
I guess I think if you change the processor, it's not the same ship, to reference the Thesius argument. Dogman is fundamentally a dog, because he has a dog brain.
