How much faster is....

.....a XP1800+ over a T-Bird 1.4Ghz in terms of woo times?

Well, I can only go by similar chips, but I've had a 1.4 TBird at 1.66GHz on a 166MHz bus and could only pull around a 4hr average. An XP1700+ at 1.75GHz on the same bus averaged about a flat 3hr per WU. So, I'd say it'd be close to an hour better overall on average...give or take a few minutes considering you're using identical platforms.
