I will be running mostly business/work/personal software (No gaming / Video encoding, etc).
For example I will be doing a lot of: Office software, Word Document, Excel, Spread sheets, Lot of web browsing & tabs, Macro/automation software (Creation & running), installing programs & creating portable apps in VirtualBox.
I am planning on purchasing used and I might OC. (I have an arctic cooler, freezer pro 7)
Wolfdale was a very serious overclocker... I remember when it first came out, computer nerds everywhere spazzed in their pants over how well they overclocked and stayed cool. I myself have a 4.0 Ghz E8400 running on the stock cooler... They were overclocked much better than the Conroe.
