You realized that's a clocked down low power processor right?
You don't want the S version. It's also more expensive than a regular version, and you can't overclock it.
You need a K version to overclock.
A 500w psu would be more than enough. Do you plan on Xfire in the future?
Oooh never knew much about intel cpu's. Thanks for that little info!
Yeah I plan on getting another gpu in the future. Also I'm thinking of using a Corsair H60/70 instead now after research today lol.
