High-core count CPUs (AMD Ryzen/Threadripper or Intel Core i9/Xeon) are ideal, as Gaussian scales well with parallel processing.

I notice you’re asking about downloading (the Windows version of the Gaussian computational chemistry software).

Simulating how molecules behave in various solvents. How to Get the Gaussian 16W Download

Gaussian 16W is the gold standard for computational chemists working in a Windows environment. It seamlessly brings the power of electronic structure modeling—from basic molecular mechanics to advanced density functional theory (DFT)—directly to your desktop. Key Strengths Unmatched Versatility

Gaussian 16W (the Windows version of Gaussian 16 ) is a commercial electronic structure modeling program. It is not available as a free download for general use; it requires a paid license from Gaussian, Inc. Relevant Papers and Technical Documentation
