Minimum system requirements for F/GO

OK, all of my computers are several years old and only have single digits worth of total RAM. I really think that it is time for me to buy a new computer. I'm not in the market for a super-expensive, custom one, just one that is modern enough for F/GO (and possibly but not necessarily Skyrim). Therefore, let's treat F/GO like a PC game for now. If it were, what would be the minimum and recommended specs for playing it on PC (CPU, GPU, RAM, etc.)? That will be my baseline for buying a new computer.
