Do I need to enable cores on my CPU?

[kieranvyas]

I've just built a computer for the first time so I'm very much learning as I go. I am running Premiere Pro CC and finding it very laggy and slow and just wondered if perhaps it wasn't utilizing all the cores on my CPU. Is there any reason I would need to enable all cores manually?

No you should not have to do as that is a very capable rig. Is this a joke?

No, Cores will be used when they are needed. If not needed, they reduce power usage to save power

I wish it was! I ripped some HD footage off youtube, threw on some Magic Bullet Looks and hit render and it's taking forever!!! I am coming from an iMac and rendering was so much quicker on there! Which makes no sense so I must be doing something wrong.
