I have noticed that for local AI at least, there is little difference between an old system (i3770/Asus P8Z77WS from 2012) which has 4 PCIe 2.0 x16 slots (supports 16/16, 16/8/8 or 8/8/8/8) running a pair of RTX3090s and up to date motherboards (with AMD9900x). Interesting to see a benchmark that bears this out - though for anyone who switches models a lot I'd assume a new system would be much quicker at that (from bandwidth improvements with newer CPUs,, nVME vs SATA and DDR5 vs DDR3).
