three things:
1, do you plan on overclock and want to have your system quiet?
- if so - add an aftermarket cooler and some thermal paste
2, do any of these three - virtualization, video encoding, rendering - matter to you?
- if not - step down to an i5
3, do you wish to upgrade your pc in the future?
- if so - haswell iX-4XXX is the way to go.
also, to consider - SSD for system /and having 2 drives helps a lot/ and a sound card /because awesome sound is awesome/...
