Decrease in Life for 2.66 to 3.8

Hello, I'm thinking of buying a computer from Digital Storm, and this prebuilt I want has a i7 920 that is overclocked to 3.8hz. I hear that CPU's usually last 10 years but overclock will decrease it faster. I want to keep this computer for about 7 years because it is a pretty expensive one. How long can I keep this computer? It is a HAF 932 model and has ASETEK liquid cooling

If your processor lasts only three years, it's replacement will cost very little at that point in time.

Frankly, the odds of your disks, vid cards, and psu failing before 7 years - or becoming inadequate for the tasks you will then ask of it - is the greater concern.

Last year, I pitched my still working P233MMX system that I had oc'd to 333 MHz.

If you keep your voltages and temperatures below Intel's recommended, your computer will go obsolete long before anything wears out from overclocking.

Yes, they will make sure they apply the correct voltage for those clocks.... no need to worry about it....

You say 7 years now but I m sure you won't keep it for that long.

When I bought my rig a year ago I said the same thing.

If you are still worried about the lifespan then underclock it to 3 GHZ.

An i7 at 3 ghz will laugh at anything.
You don't need 3.8 GHz performance for now.
