What is the most powerful processor that will fit the NF520-A2 SE (Socket AM2) motherboard?

Question

AMD

In 2017, I successfully upgraded my ancient hardware to Intel Xeon 4x3GHz.

At the time of asking this question, there is an ancient computer with an NF520-A2 SE motherboard :

• SocketAM2
  
• Supports AMD Athlon 64 X2/64/FX/Sempron Processors
  
• Hyper Transport Technology up to 2G
  
• Supports AMD Cool'nQuiet Technology
  
• Supports BIO-Remote 2 Technology
  
• Supports Charger Booster Technolog
  

I want to give it a second life by inserting the maximum possible processor power.
From aliexpress or from another store, new or bushy - it's not so important.
Having rummaged through the Internet, I found that AM2 + can be inserted into this socket, but I still did not understand whether this would increase performance?
Will it be possible to insert a quad-core processor, for example, this one ?
And how to check in advance whether it will be possible to find the BIOS firmware and actually reflash it?
What else do you need to pay attention to?
