VIA C3 800A
A lot like this VIA C3 800A except that this is the socket S370 variant. Performance-wise it will be identical but being a socketed CPU the choice of motherboard is still possible which could work out positively in terms of performance.
I haven't benchmarked it yet but whenever I have my S370 running again I'll benchmark the VIA C3 CPU's I have collected.
This version of the C3 800A doesn't have SMD chips on top despite that the contact points on top of the CPU are available. I have another C3 800A that does have the SMD's on top.
