I recall a couple of years ago the guy who was supposedly a great authority on MC safety
(I forget his name, but he wrote regular magazine columns on "MC safety" -- an oxymoron if there every was one

)
was killed

when he collided with a deer -- riding at night. It seems to me your risk of accident goes up
dramatically after dark

, and it does not take rocket science to reach this conclusion.
Long ago I swore off riding at night -- you can't see the road surface (duh

), which is IMHO
essential to keeping the rubber side down.
Back to new PC builds: What is the current thinking on the expected service life for a high-end gaming rig?
I have thought that when the rig can no longer play at least half of the newest
games on all-max settings, it is then obsolete for gaming and can be retired to ordinary desktop
applications. Call this the rig's "half-life" ?
Up until my recent build, my rigs were "mid-range", and they never were quite able to play
newest games on all-max settings, but they did OK. At 3-4 years, it got harder to find new games that
could be run on high settings, so the rig got an Ubuntu install & went over to the office.
Now, getting to the point: I would like to think my new rig, which I believe is fairly "high-end", should have a
"half-life" of 5 years or so

. Hence, I would like to keep it alive at least that long (not drive it so hard that
processors, etc. start to burn out). This is why I have been fishing for good operating temperature ranges for my
Core i7-3960X, a safe range that I know will not fry anything for at least 5 years.
