I have a tech question for you guys
I have an almost ancient Alienware R4 with a Vega 64 and a 3930k 
It's a pcie 2.0, ddr3 motherboard, would a newer motherboard with ddr4 memory and at least pcie 3.0 make a big difference, or should I just go all in and build a whole new PC? 
I'd likely need a new case to upgrade the motherboard anyway.
