You’d be better off adding Express Generator and using that instead of Chrome to generate strategies before spending more money upgrading hardware I think. In your situation you’d be looking at a new CPU, motherboard, and probably RAM as well. A high core count Intel 13th Gen or Ryzen 9 would definitely make a bigger difference, but at a greater cost of investment, and you’d still want to switch to Express Generator over opening more browser tabs to maximize the performance. Express Generator is just SO much faster and more efficient, on any platform, that it probably makes more sense to invest in that first and hardware later. At the end of the day though, more cores is going to get more done when multitasking, no way around it. Also, you can run Express Generator on more than one computer if you have them, dividing up symbols between different machines. Scripting everything is SO much easier and faster than configuring multiple browser tabs. I generate strategies on 28 pairs daily just by double clicking a script and letting it run.
