OK I'm working on a modest budget upgrade. I currently run an x99 5820k 6 core 12 thread which is ancient now by todays standard. I was thinking of getting an e5 2680 v4 or 2690 v4 which are also old I Know but have more cores. Obviously these have more threads but slower clock speed than i7 5820k. Would I see much increase in render speed in LW if I upgraded to an e5? Or is it not really worth it? Would there be any down sides. I don't game, I use LW, Adobe after fx, marmoset, substance painter, zbrush.
