He's using DxO not Lightroom, and also consider the pricing on that chart. The 2700x is $260 vs the i5 9600K $370, thats about $100 more for 2.5% performance increase in Lightroom. There is nothing else on that chart in that price range. The Ryzen has a better multi core score on Geekbench so will probably be better on DxO. The 2700x isnt 4x as powerful as your current CPU, so there must be something else in there as well other than just cpu performance. An SSD makes life in general more pleasant for anything really. Having your catalogue on an internal SSD would be better for reviewing, editing, etc as well. Do you find rendering slower or faster on DxO? Just curious, 2 mins sounds like a lot to me.
