My network connection was driving me nuts. For some reason it started trying to connect by wired connection even though it NEVER has. The wireless connection kept disconnecting and Network would show my network as being out of range. This is a dektop. Nobody is moving it.
I purchased my i7 2600k when it released over 2 years ago at $330 and I have to say it was one of my best investments yet when it came to hardware. I run it daily at 4.6 GHz (stock volts) without an issue and pretty much runs anything I throw at it with ease.
