Ghengis,
I am a geophysicist/geologist/engineer earth scientist, and place very serious demands upon my SP3, including Excel spreadsheets with VBA macros, Python to VBA, Matlab, brute force Assembly modules, Java applets to access databases of seismic and electronic measurements, and also handle a quarry-load of administrative tasks with Outlook mail, VNC connections, VPN connections, and PowerPoint. Also, some of these systems and databases are old or home brew.
Since I do 3D forward modeling, speed and efficiency of computing and graphics is very important. Otherwise, I could not afford to do "what if" analysis, because computer iterations would be slower than the cognitive experimentation and exploration.
I use 64-bit Office 2013, but 32-bit would work just as well, or maybe even faster, in the non-communication number crunching.
Sluggish behavior on some machines is most often because of TSR (terminate-and-stay-resident) programs (services) are designed or deployed inefficiently - or unnecessarily.
I not only did all my work on a Surface Pro 3 i7 512 + 128GB microSD, with Windows 8.1, but I now do it with an experimental Windows 10 build.
Funny thing is,
a typical gamer needs more computing power than outlined above. There are many as members of this forum, for whom I have very high regards.
