I was considering swapping my old Lenovo G560 for an i7 840QM, but I want to make sure it works.

What is the cost for that CPU? If it's over 20$, selling the laptop might be smarter. The RAM is cheap, 4GB costs around 4$, and 8GB is about 8$. The 840qm seems outdated, drawing a lot of power which reduces battery life and may strain the cooler. It's better to sell the laptop and buy a used 4th or 8th generation model. They'll use less power and perform better, even with an i5, because the i7 likely has a very low boost clock. The single-core 3.2GHz doesn't matter much if the core is only ~2GHz. My mom's laptop is broken, but her is an i5 4200U with 2.3GHz all-core. I can give a rough idea for Haswell with a downclocked i3 and some X58 Nehalem CPUs, but performance estimates will be off due to DDR3 and the 840qm's design. Expect a bit higher than actual performance.
Thanks. The laptop comes with built-in graphics, so I was thinking about a modest upgrade of $20-30. After that, selling the device and maybe getting a newer model with an i5 processor would be the next step.
