Triple check the specs of your iX processor to make sure it supports Intel Quick Sync which will allow Plex to use Hardware Acceleration. This is yet another pretty good way of diverting load off the processor and getting more bang for your buck.(Plex Pass required to enable the feature)
Any i3/i5/i7 from late 2011 onwards will have Quick Sync Video. Rule of thumb is if it has USB 3.0 on the motherboard then the CPU will have Quick Sync Video.
