Snort's not hard limited anywhere but there's more to building a gigabit IDS than just putting it on a fast box. Drivers, OS configuration, proper hardware selection and careful performance tuning are all required. You can do it with just open source software and off the shelf Dell/whatever gear if you're willing to write your own drivers for the specific NICs you're using or buying something like Endace cards, but even with that you've only solved the sensing side of the problem. There's also the sensor management, data management and analysis/reporting that makes the IDS useful to the users, and some of that stuff is extremely non-trivial to build.
People can do the math themselves and figure out where the time/ convenience/money tradeoff for their organization lies, but building a gigabit (high packet per second) IDS is still pretty tough even on today's systems.
