|The E6600 designation was used for two different CPU's, a Pentium series in 2010 and an early Core 2 series in 2006. From the speed it appears to be the Pentium:|
An inexpensive alternative to the later Core 2 series but with less cach. Though it should be nicely overclockable, it is not an i-3 in it's architecture, does not fit the same motherboard, and should have been less expensive than the i-3.
If you just purchased a computer or are just building a computer you should have gotten the SECOND GENERATION i-3 with a board that uses the socket 1155, unless you are really doing a budget system and got a really good deal on it.
It is quite normal for a CPU to jump up to 90-100% when you are starting a program or running a game or an intense program. You DO want the processor fully involved in what you want it to do at the time so as long as it slows back down when you shut down things, all is normal.
If you were misled into purchasing the wrong thing, try returning it, but you will probably need to switch the CPU, Board, and RAM. If you are gaming or want to use graphics intensive programs, you can improve performance bu adding a distinct graphics card if you are using the onboard graphics.
You have to be a little bit crazy to keep you from going insane.
