Tony, I moved from a Abit KT7/Athlon 1.2GHz/512MB PC133/ATA66 system to a Soyo Dragon+/Athlon XP 1.4Ghz/1GB PC2100 DDR/ATA100 system this past December. The newer system is definitely much "snappier" across the board.
I don't autoroute PCB's, but I do some CPLD design work with Cypress' Warp VHDL tools and the newer system is about 25% faster than the old one. I'd attribute this to the fact the system has about 50% more memory bandwidth available. CPU speed increase and improved HD access times are somewhat a (lesser) factor. I also recently built an Abit nForce chipset Athlon XP system for my PCB designer. It has even better memory bandwidth than the Soyo and is also very "snappy". So yes, the newer memory architectures, chipsets and CPU's tend to make a difference -- but it really all depends on the specific motherboards, BIOS settings, etc. and how you actually use your system.
