Depends on the investment.
You're looking at a 12-year-old processor, that barely has as much power than an entry level laptops sold two years ago.
When buying a refurb, especially with an Intel processor, 6th gen Core i5 is where we advise our clients to start. As an example, here is an HP model.
It's got a smaller footprint, a CPU that consumes less power but has higher performance, a larger SSD, It just doesn't have a slow hard drive to hold it back.
We have clients looking along the same lines.
And for about the same money, you can purchase a more powerful model
Well some of our clients, lean more towards this Dell model
To perform properly with Illustrator, it will need a dedicated graphics card
AMD Radeon RX 550 4GB GDDR5 PCIe DP 2 x Mini DP Low Profile Graphics Card R9J9P
This card will work with both models. Although it is suggested to get quality cables, depending on the monitor or television you're connecting it to.
Although not definitely required, most people run in Adobe eventually upgrade to 32GB
But you can basically be done at any point.
Hope this information helps
