pc out pc in

Hi guys n girls, ive decided its time to start a complete new pc gaming rig from scratch, ive owned my current pc for 15yrs allowing for the odd component upgrade ect of course, but the time has come to move on.

Im planning an sli rig with an i7 prossesor, aswell as gaming i also require it for music editing and production.

Just thought id get some thoughts from other people about the best root to take?

Cheers
