My wife was out of town yesterday - a rare occurrence, we are seldom apart - and of course I got up to some nonsense. Pretty benign nonsense, but somewhat indulgent nevertheless.
Our main home PC is a home-built affair, it's several years old and also quite unremarkable. I previously upgraded the hard drive to an SSD (a great upgrade, I have to say), and that's been about it.
Anyway, it was built with an Intel dual core processor because that was available and cheap at the time, although the motherboard actually supports a quad core cpu.
