My old computer would load instances first... 2 instances of wow, and my main machine would load 5+ seconds after it... (3 instances of wow). now my new computer seems fast and my old computer is 5+ seconds after it. Can't say I did any benchmarks before / after beyond noticing it go faster. As with any upgrade your mileage will vary depends on your current setup. I'm not sure I've seen a post on here of anyone who didn't love a SSD once they got it though.
