I am getting a P55A-UD4 and an i870, as a backup board. As per Anandtech benchmarks, the performance of i7 870 is slightly better / comparable to similar 4 core i7 9xx cpus.
Looking at other build logs here on Vogons, I see no reason why P55 would be less compatible than x58 for windows 98.
I do agree that x58 is a nicer platform: 6 cores, triple channel ddr3, more pcie lanes and better boards /better OC.
