I have use the software in the past on a computer center and I find it very helpful for my research. However, I have never use the software to run directly on a Windows computer. Since the IT shop people in our department are not familiar with the software, I have few questions that I was hopping you could help me answer. Taking into account that the type of calculations we would run are on organic small molecules (ground states, Transition states, TDDFT and similar) and are not high performance computer demanding, we will probably use medium size level such b3lyp/6-31g(d,p), then the questions are: 1. If we buy a multicore processor (quad core for example) can the software use all cores without the installation of any extra software? 2. Are there any specifications on the computer hardware and software that you would recommend.
