New Setup -
Geforece 970GTX 4Gb VramDDR5
16Gb DDR3 2600 Mhz cas 9 latency
Intel i7-4790k 4.0Ghz Processor 11.2k CPUmark

When I originally switch video cards, little to no noticeable frame difference, same as switching the ram to higher quality gaming ram. It appears the switch of processors greatly increased my framerate.
