This is probably one of those things where it depends.
My experience was the other way around. I was seemingly stable for over a year (including numerous hours of Prime 95, at least twice overnight and then some, plus hundreds of gaming hours), but apparently it wasn't totally stable, as it crashed during, of all things, The Sims 3 one day. I asked around, someone suspected the CPU, and had me try Intel Burn Test, which I heard of but never used. That caught instability in minutes. I use it primarily now, and will use Prime 95 during longer tests and as a secondary/alternate option.
